Don’t forget to clean up unused docker volumes once in a while...

I’ve started the process of setting up the new network at work. We got a 1Gbit fibre connection.

Plan was simple, move all cables from old switch to new switch. I wish it was that easy.

The imbecile of an IT Guy at work has setup everything so complex and unnecessary stupid that I’m baffled.
We got 5 older MacPros, all running MacOS Server, but they only have one service running on them.

Then we got 2x xserve raid where there’s mounted some external NAS enclosures and another mac. Both xserve raid has to be running and connected to the main macpro who’s combining all this to a few different volumes.

Everything got a static public IP (we got a /24 block), even the workstations. Only thing that doesn’t get one ip pr machine is the guest network.
The firewall is basically set to have all ports open, allowing for easy sniffing of what services we’re running.

The “dmz” is just a /29 of our ip range, no firewall rules so the servers in the dmz can access everything in our network.

Back to the xserve, it’s accessible from the outside so employees can work from home, even though no one does it. I asked our IT guy why he hadn’t setup a VPN, his explanation was first that he didn’t manage to set it up, then he said vpn is something hackers use to hide who they are.

I’m baffled by this imbecile of an IT guy, one problem is he only works there 25% of the time because of some health issues. So when one of the NAS enclosures didn’t mount after a power outage, he wasn’t at work, and took the whole day to reply to my messages about logins to the xserve.

I can’t wait till I get my order from fs.com with new patching equipment and tonnes of cables, and once I can merge all storage devices into one large SAN. It’ll be such a good work experience.

I am the manager of a customer service team of about 10-12 members. Most of the team members are right out of school and this is their first professional job and their ages range from 22-24. I am about 10 years older than all of my employees. We have a great team and great working relationships. They all do great work and we have established a great team culture.

Well, a couple of months ago, I noticed something odd that my team (and other employees in the building) started doing. They would see each other in the hallways or break room and say “quack quack” like a duck. I assumed this was an inside joke and thought nothing of it and wrote it off as playful silliness or thought I perhaps missed a moment in a recent movie or TV show to which the quacks were referring.

Fast forward a few months. I needed to do some printing and our printer is in a room that can be locked by anyone when it is in use (our team often has large volumes of printing they need to do and it helps to be able to sort things in there by yourself, as multiple people can get their pages mixed up and it turns into a mess). The door had been locked the entire day and this was around noon, and the manager I have the key to the door in case someone forgot to unlock it when they left. I walked in, and there were two of my employees on the couch in the copier room having sex. I immediately closed the door and left.

This was last week and as you can imagine things are very awkward between the three of us. I haven’t addressed the situation yet because of a few factors: This was during both of their lunch hours. They were not doing this on the clock (they had both clocked out, I immediately checked). We have an understanding that you can go or do anything on your lunch that you want, as long as you’re back after an hour. Also, as you mentioned in your answer last week to the person who overheard their coworker involved in “adult activities,” these people are adults and old enough to make their own choices.

But that’s not the end of the story. That same day, after my team had left, I was wrapping up and putting a meeting agenda on each of their desks for our meeting the next day. Out in broad daylight on the guys desk (one of the employees I had caught in the printing room) was a piece of paper at the top that said “Duck Club.” Underneath it, it had a list of locations of places in and around the office followed by “points.” 25 points – president’s desk, 10 points – car in the parking lot, 20 points – copier room, etc.

So here is my theory about what is going on (and I think I am right). This “Duck Club” is a club people at work where people get “points” for having sex in these locations around the office. I think that is also where the quacking comes into play. Perhaps this is some weird mating call between members to let them know they want to get some “points” with the other person, and if they quack back, they meet up somewhere to “score.” The two I caught in the copier room I have heard “quacking” before.

I know this is all extremely weird. I wasn’t even sure I wanted to write you because of how weird this seems (plus I was a little embarrassed). I have no idea what to do. As I mentioned above, they weren’t on the clock when this happened, they’re all adults, and technically I broke a rule by entering the copier room when it was locked, and would have never caught them if I had obeyed that rule. The only company rule I can think of that these two broke is using the copier room for other purposes, preventing someone else from using it.

I would love to know your opinion on this. I tend to want to sweep it under the rug because I’m kind of a shy person and would be extremely embarrassed to bring it up.

Me: If humans lose the ability to hear high frequency volumes as they get older, can my 4 week old son hear a dog whistle?

Doctor: No, humans can never hear that high of a frequency no matter what age they are.

Me: Trick question... dogs can't whistle.

Tldr: fucked up windows boot sector somehow, saved 4 months worth of bachelor thesis code, never hold back git push for so long!

Holy jesus, I just saved my ass and 4 months of hard work...
I recently cloned one of my SSDs to a bigger one and formatted the smaller one, once I saw it went fine. I then (maybe?) sinned by attaching an internal hdd to the system while powered on and detached, thinking "oh well, I might have just done smth stupid". Restart the system: Windows boot error. FUCK! Only option was to start a recovery usb. Some googling and I figured I had to repair the boot section. Try the boot repair in the provided cmd. Access denied! Shit! Why? Google again and find a fix. Some weird volume renaming and other weird commands. Commands don't work. What is it now? Boot files are not found. What do I do now? At this point I thought about a clean install of Windows. Then I remembered that I hadn't pushed my code changes to GitHub for roughly 4 months. My bachelor thesis code. I started panicking. I couldn't even find the files with the cmd. I panicked even more. I looked again at the tutorials, carefully. Tried out some commands and variations for the partition volumes, since there wasn't much I could do wrong. Suddenly the commands succeeded, but not all of them? I almost lost hope as I seemed to progress not as much as I hoped for. I thought, what the hell, let's restart and see anyway. Worst case I'll have to remember all my code😅🤦.
Who would have thought that exactly this time it would boot up normally?

First thing I immediately did: GIT PUSH --ALL ! Never ever hold back code for so long!
Thanks for reading till the end! 👌😅

I run update without where on mysql console on production database Today.

CLASSIC

Just because I needed to fix database after bug fix on the backend of the application.
I thought I wrote good sql statement after executing it on my local machine and then everything got bad.

Luckily it was only one column with some cached statistics data and I checked that it was not important data before I actually started fixing stuff but still ...
Almost got hard attack afterwards.
Made a script to fix this column and it took me only 15 minutes but still...

Bug was caused in part I got no unit tests and application grow after 3 years of development from simple one for one customer and volumes of documents around 50k to over 40 customers and volumes over 2mil per month, don’t know how many pages each, just in one year after we completed all needed features.

I have daily backups and logs of every api operation but still.
I think this got to far for one backend developer.

I got scared that I will loose money cause I am contractor and the only backend developer working on it.
I am so tired of this right now I think I need a break from work.

Responsibility is killing me so hard right now.
It will take a week to get back to normal.

I am scratching my head since 2 days cause a rather large Dockerfile doesn't work as expected.

CMD Execution just leads to "File not found".

Thanks, that's as useless as one ply toilet paper...

Whoever wrote the Dockerfile (not me…) should get an oscar...

Even in diarrhea after eating the good one day old extra hot china takeout from dubious sources I couldn't produce such a dumpster fire of bullshit.

The worst: The author thought layering helps - except it doesn't really, as it's a giant file with roughly 14 layers If I count correctly.

I just found out the problem...

The author thought it would be great to add the source files of the node project that should be built as a volume to docker... Which would work I guess....

Except that the author is a clueless chimp who thought at the same time seemingly that folder organization means to just pour everything into one folder....

Yeah. That fucker just shoved everything into one folder.

Yeeeeeesssssssss.

It looks like this:
source
docker-compose.mounts.yml
docker-compose.services.yml
docker-compose.yml
Dockerfile-development
Dockerfile-production
Dockerfile
several bash scripts
several TS / JS / config files
...

If you read the above.... Yes.
He went so far to copy the large Dockerfile 3 times to add development and production specific overrides.

I can only repeat what I said many times before: If you don't like doing stuff, ask for fucking help you moron.

-.-

*gooozfraba*

Anyways...

He directly mounts this source directory as a volume.

And then executes a shell script from this directory...

And before that shit was copied in the large gooozfraba Dockerfile into the volume.

Yeeeaaah.

We copy stuff inside the container, then we just mount on start the whole folder and overwrite the copied stuff.

*rolls eyes* which is completely obvious in this pit latrine of YML fuckery called Dockerfile.

As soon as I moved the start script outside the folder and don't have it running inside the folder that is mounted via volume, everything works.

Yeah.... Maybe one should seperate deployment from source files, runtime related stuff from build stuff.

*rolls eyes*

I really hate Docker sometimes. This is stuff that breaks easily for reasons, but you cannot see it unless you really grind your teeth and start manually tracing and debugging what the frigging fuck the maniac called author produced.

You know what is really a dick move? It’s when devs start a literal timer once someone messages them, and once the timer is up, they read the message. Sometimes this can be like 30 minutes of minimum wait time for just a simple fucking question. This really pisses me off and speaks volumes to all the other devs (who they should actually make an attempt to collaborate with). Fucking inconsiderate assholes.

At work everybody uses Windows 10. We recently switched from Vagrant to Docker. It's bad enough I have to use Windows, it's even worse to use Docker for Windows. If God forbid, you're ever in this situation and have to choose, pick Vagrant. It's way better than whatever Docker is doing... So upon installing version 2.2.0.0 of Docker for Windows I found myself in the situation where my volumes would randomly unmount themselves and I was going crazy as to why my assets were not loading. I tried 'docker-compose restart' or 'down' and 'up -d', I went into Portainer to check and manually start containers and at some point it works again but it doesn't last long before it breaks. I checked my yml config and asked my colleagues to take a look. They also experience different problems but not like mine. There is nothing wrong with the configuration. I went to check their github page and I saw there were a lot of issues opened on the same subject, I also opened one. Its over a week and I found no solution to this problem. I tried installing an older version but it still didn't work. Also I think it might've bricked my computer as today when I turned on my PC I got greeted by a BSOD right at system start up... I tried startup repair, boot into safe mode, system restore, reset PC, nothing works anymore it just doesn't boots into windows... I had to use a live USB with Linux Mint to grab my work files. I was thinking that my SSD might have reached its EoL as it is kinda old but I didn't find any corrupt files, everything is still there. I can't help but point my finger at Docker since I did nothing with this machine except tinkering with Docker and trying to make it work as it should... When we used Vagrant it also had its problems but none were of this magnitude... And I can't really go back to Vagrant unless my team also does so...

Few years ago when I was new to command line....

I was in love with it....

I decided to format my pd via cmd...

It was a very simple task though i was soo happy and I did it....

Closed cmd....

Went to thispc...

And my pd was full as it was before....

I was like lets do it again.....

I opened cmd....

Got the list of volumes​ n was stunned.....

Until now i had no idea that i had formatted some​ other volume....

I opened thispc and saw a 700gb volume which was red earlier turned white.....

OMFG....

I cant explain what happened further....

Confession: I know how to use Git but I want to learn how to use it properly so my team won't crucify me.

Docker y u no mounting volumes on Windows anymore...?

World y u use Windows at all?

Note to self, y u no problem-solving instead of devrant posting?

My journey into learning Docker, chapter {chapter++}:

Today I learned that when you use a database image in your docker-compose file, and you want to rebuild the whole thing for reasons (say, a big update), then if you change your credentials ("root" to "a_lambda_user" or change the db's password) for more security, and you rebuild and up the whole thing... It won't work. You'll get "access denied".

Because the database (at least mysql and mariadb) will persist somewhere, so you need to run "docker rm -v" even though you didn't use any volumes.

I love loosing my fucking time.

I love Docker but I'm almost always screwing around with permissions and file ownership when it comes to secrets, bind mounts and making sure shit doesn't run as root while also making sure secrets are exposed and volumes aren't owned by root

Perhaps my frustration comes from the fact that I'm still learning and sometimes get impatient when things don't work within an hour or two, but still

When your IT VP starts speaking blasphemy:

"Team,
We all know what’s going on with the API. Next week we may see 6x order volumes.

We need to do everything possible to minimize the load on our prod database server.

Here are some guidelines we’re implementing immediately:

· I’m revoking most direct production SQL access. (even read only). You should be running analysis queries and data pulls out of the replication server anyway.
· No User Management activities are allowed between 9AM and 9PM EST. If you’re going to run a large amount of updates, please coordinate with a DBA to have someone monitoring.
· No checklist setup/maintenance activities are allowed at all. If this causes business impact please let me know.
· If you see are doing anything in [App Name] that’s running long, kill it and get a DBA involved.

Please keep the communication level high and stay vigilant in protecting our prod environment!"

RIP most of what I do at work.

No actual data loss here, but the feeling of data loss.

After having my data scattered across several devices i decided to get a grip on it use a cloud. I'm too paranoid for a real cloud so i used a local nextcloud installation. That was done via docker and with a 2TB raid1-array.
I noticed that after restarting the server the cloud was somehow reset and pointed me to the setup-page, afterwards my files were already there. It did strike me as odd but i figured "maybe don't restart the server in the next time".
But i did restart it. And this time i had to setup the cloud again, but my files were gone. I got close to a heart attack, even though all those files weren't that valuable. I ripped one disk from the usb hub, connected it to my laptop and tried to mount it, but raid array. Instead i started photorec and recovered a bunch of files, even though their names were some random hex and i knew i'd spend my next weeks sorting my files. While photorec ran i inspected the docker container and saw that there were only 10GB of space available. After a while and one final df i found the culprit: the raid. For some reason the raid wasn't mounted at boot and docker created the volumes on the servers hard disk, same goes for the container data. After re-adding the disk to the hub i mounted the raid and inspected everything again. All my files were still there.

At no point did i lose my data, but the thought was shocking enough. It'd be best not to fiddle with this server in the next time.

It was about 2:30am.. The darkness had been dominating the outside for a while, and I was having issues with my partitions on my CentOS server. Yup that's correct. I think.

I really wanted to go to bed. Last thing I had to do, was re-allocate some space from centos-home to centos-root. But I fucked up, of course I did.
After about half an hour of making food and trying different stuff to solve the "Can't read superblock error" error, I found an answer that just lead to "Can't read secondary superblock error, sorry".
At least they apologize now lol.

I ended up trashing the centos-home volume (is volume and partition the same ?) and just smashing it all onto centos-root. I lost some data, but screw that, stuff is working and I'm not going to bed.
Yeah, stuff is working. I hope. No errors encountered yet.

Moral of the story: Home partition isn't needed and it's okay to kill it

Hell of a Docker

One application in c++. 4 in c# targeting Linux. Several logging places, Several configuration files , dozens of different folders to access (read/write). Many applications being called from just one that orchestrates everything.

OS is Linux. Installation is to be made inside a docker image and later placed in a container by means of several bash files and python scripts. All these are part of a legacy set of applications.

They’ve asked me to just comment out one line which took 3 days to find out because they didn’t remember where it was and in which application it was and what was in that line.

After changing it, I was asked to create a test environment which must have resemblance to the current server in production. 12 days later And many errors, headaches, problems with docker, I got it done.

Test starts and then, problems with docker volumes, network, images, docker-composer, config files and applications, started to appear.

1 month later, I still have problems and can’t run all applications at least once completely using the whole set.

Just one simple task of deploying locally some applications, which would take one or two days, is becoming a nightmare.

Conclusion: While still trying to figure out why an infinite loop was caused by some DB connection attempt in an application, I am collecting a great amount of hate for docker. It might be good for something, that’s for sure, but in my experience so far, it is far worse than any expectations I had before using it.

Lesson learned: Must run away from tasks involving that shit!

Yesterday I tried Rancher on a DigitalOcean droplet.

Rancher itself was easy to startup and use. But I couldn't manage to find the Container Volumes on my NFS Server. Even the NFS Server was up and running.

I really felt like a monkey in front of my PC not understanding what Im doing.

Pet peeve: when I search for Java related jobs and got JavaScript jobs in return

I've never been a big fan of the "Cloud hype".

Take today for example. What decent persistent storage options do I have for my EKS cluster?

- EBS -- does not support ReadWriteMany, meaning all the pods mounting that volume will have to be physically running on the same server. No HA, no HP. Bummer

- EFS -- expensive. On top of that, its performance is utter shit. Sure, I could buy more IOPS, but then again.. even more expensive.

S3 -- half-assed filesystem. Does not support O_APPEND, so basically any file modifications will have to be in a
`createFile(file+"_new", readAll(file) + new_data); removeFile(file); renameFile(file + "_new", file);`
way.
ON TOP of that, the s3 CSI has even more limitations, limiting my ability to cross-mount volumes across different applications (permission issues)

I'm running out of options. And this does not help my distrust in cloud infras...

I’m a neat guy and gosh darn it people like it when i yell at them
It stirs something above and below in them to hear precisely what is wrong with them at high earnestly hateful volumes before the salty taste

Is there any kind of protocol/method where I can use something like docker containers in order to "host" compilers like gcc and use that with vscode to compile and assemble source code?

No I'm not talking about volumes (it's a bit tedious if I want to use it to manage numerous projects)

Anyone know of a good docker backup tool?

I'm working with fairly limited space here so Im looking for a tool to allow me to backup and restore my docker instance without storing easily recreatable data.

That means that what I want to backup are:
- Container specs (inspections or the like)
- Contents of persistent, non-nfs volumes

Since the image and the contents of my nfs volumes are stored elsewhere, and my space is limited, I decided not to back them up. Same for non-persistent (unnamed) volumes since they mostly contain stuff that you don't want to recreate on every container update or recreation but can easily be recreated if needed.

The hope is that this approach should give me a pretty slim backup while still preserving everything I need to recreate my whole docker instance.

Thanks in advance!

Any ColdFusion devs in here? I've been plying with it for a while; Nice Java framework, quick to deploy. Feels like it could struggle under high request volumes though..?

I always hear that Java EE is dead. can someone explain?

Before he began dropping the 20K proposed to remodel my flat, I told my father I much preferred a contractor who was recommended by someone I knew, as opposed to using a big corporation like Home Depot. FAMOUS LAST... a neighbour in my building highly recommended the contractor we chose. And, week 7 [or is it 8?] of what was proposed to take no longer than two weeks has begun afresh!
On Friday the fellow who is the owner of the contract remodeling company was here touching the paint. He was here because I forbade the two painters he sent to do the initial painting job.
My internet cut out suddenly around 1300 Friday. He set to leave for the weekend shortly after that. I mentioned the outage to him. The essence of his reply was that there was no way it could have had anything to do with him. The following day, my internet provider sent a tech out to diagnose the problem. What was the problem? The head of the remodeling firm removed a face plate from the wall where there were telephone wires and disconnect them when he tore the wires as he replaced the face plate.
Although the tech told me he wasn't going to charge my account the $85.00 fee for his services because the outage was caused within my flat, I wish to be sure of this. Which brings us to the punchline.
My internet provider is a lame ass business model, dreamed up by a squint-eyed ex-circus monkey, never well endowed in the top story, and now just plain sad.
There were some 911 outages in Washington State last Thursday night. All during the day Friday when you dialled their freephone #. the recorded announcement, before saying anything else, told you they were experiencing heavier than usual call volumes, and my wait would be greater than `10 minutes. Fine. What fried my La Croix silk was that after their customer service dept closed for the weekend, that outgoing message remained.
Today, I wanted to contact my provider to see if they would know if the $ was going to be charged to my account. After pressing the 'send' key, my computer came back with an error message, saying they were having technical difficulties. So, I went on over to the 'chat' page. There's nothing to click on to take me to this enfabled location. So, can't reach them by phone unless I want to hear, every 30 seconds whether or not I wish to, how sorry they are for my delay.
A few years ago I would've used this as an excuse to have a technicolour meltdown. The reason I'm posting this is that I am now able to see beforehand what I'll be doing to myself getting upset over the circumstances. When I do reach somebody, I'm going to tell them as lightly as possible, that if they were an airline, I wouldn't board any of their aircraft. Ever.
