#containers
Hey #kubernetes knerds, check out the latest @headlamp blog about their plugin management UI.
Now it's even easier to extend and build out your own Kubernetes #UI experience!
@hgutoot Yes. You're right. Several programs are available for managing containers. There are several container runtime solutions and several orchestrators. This is what I always tell when someone asks. 🤓😉
The main topics when someone want to know more: OS-level virtualization, Containerization, Container Orchestration Tools

Where to find official MySQL container images ?
If you are deploying MySQL on containers, one of the first tasks is to find the right image.
There's a certain amount of confusion, especially when we're trying to help someone who's having problems with their deployment.
For example, when people say I'm using the official docker image... what does that really mean?

@jarkko likely due that if you build the next images, each previous layer just gets reused. Each Containefile CMD creates a new layer. There is also the non "bud" way where you specifically create layer only at commit. Then you control when you create the image layers.

#selfhosting #docker #podman #containers #databases #database #postgresql #SQL
self-hosting newbie here. Is it worth centralizing all my databases onto one container, or is having a container for each service the best approach?
So, recently I was disappointed in Podman for deprecating podman-generate-systemd so quickly in favor of quadlets, a standalone tool that is now merged into podman.
#Quadlets are effectively #systemd units that run #containers and are a direct replacement to #compose files, be they for #Docker or #Podman. That is pretty cool. They also fix certain issues like services losing validity when running podman-compose after major changes to the compose file, and it makes the systemd units much more readable, so it's good to migrate to them in the long term.
What bothered me was that quadlets don't really replace podman-generate-systemd, they only replace compose files, which is not always an option.
I found out today that podlet exists, in a LinkedIn post of all things. It can convert compose files and podman commands into quadlets, which is exactly what was needed to make quadlets an actual replacement.
I'm hoping #podlet fares well.

3. some connections are slow to start but work (apt update).
4. some connections are extra slow (git clone)
5. npm install still hangs

Something strange happened to me today. A developer reached out because after restarting some #docker containers, nginx seemed to be behaving oddly. I connected and realized something big was off. It appeared to be a different container, bloated, and nginx wasn't even starting. After ruling out the possibility of the nginx image from the docker registry being compromised, we started to brainstorm. Long story short, another developer had created a custom image and named it "nginx," so the dockerfile was pulling it directly from the local setup... #DockerTroubles #Linux #Containers

I've been thinking of a cli tool, that helps people craft #containers files, something on the lines of: start a new interactive shell session that is based on the FROM declaration in the container file, then before and after every command a snapshot is made, you can easily revert, delete or mark/promote commands to/from the container file, and every command run needs to be in the same environment as to when building it (think env vars)

I'm looking to switch from multi-booting my laptop to one linux distro that hosts purposed containers (work, personal, play, etc).
Any recommendations or ideas on the best way to do this?
I want to keep them separated and secured with different credentials, but minimize the pain in the ass that is rebooting and entering multiple passwords every time I want to switch contexts.
Virtual machines work, but they have a lot of overhead.

Incus Project: A Breakaway from Canonical’s LXD
https://linuxiac.com/incus-project-lxd-fork/
In response to Canonical’s takeover of LXD, the independent Incus project arose as a fork for this container and virtual machine manager.
Whilst we all know #containers started with the #Docker --privileged flag are insecure and it's possible to break out of them, there aren't always a lot of practical examples of how that's done.
So I've got a quick example here of breaking out of a privileged container using a kernel module

Back in the day, "There's More Than One Way To Do It" (TMTOWTDI) was the motto of #perl, and it was definitely a feature, not a bug.
In the last 30 years though, TMTOWTDI (aka "tim toady") is a concept that's spread through every aspect of technology, and has grown to the point that there are now *too many* ways to do it - decision paralysis is the most common reaction to starting new projects or trying to solve problems (that, or just going with what you already know and ignoring the rest). See for instance how many zillion ways there are to run #containers on #AWS (thanks, @Quinnypig ).
I wonder if we have not swung so far towards the capability end of the spectrum that we have completely lost sight of the power of simplicity, and the dangers/tradeoffs of #complexity.
(On the other hand, all this complexity keeps technologists like yours truly employed. ¯\_(ツ)_/¯ )

Hey #dotnet SDK #docker #containers folks - I made an experiment over the weekend: https://gist.github.com/baronfel/f421c15d8678002753e902f8aa54d694
Add this Directory.Build.targets and make images for all of the TargetFramework(s) or RuntimeIdentifier(s) in a project/solution at once with `dotnet build /t:Containerize`
I've been playing with this and it feels pretty nice. This is a single project with linux-arm64 and linux-x64 RIDs, but then I added another for linux-arm on the second run. This would work for solutions as well.

Despite being high level this is actually a fairly useful list: it gives you a language and framework to talk about security issues that can be shared between upper management and rank-and-file members.
It's useful… until marketing and sales groups get their hands on it.
Then, as with #SOA, #microservices, #NoSQL, #containers, and so many other things… you start to get a lot of "this miracle product will protect you from the OWASP API Top 10 Threats!!!!! Just pay us monies!"
