Answered 2022-Mar-10 at 10:40

There are two ways to set environment variables in a Dockerfile. ARG values are only visible in RUN instructions, and can't be changed after the image has been built. ENV values are visible while the container is running to (in the ENTRYPOINT/CMD) and can be changed when the container is run, but can't be directly set at build time.

Since this is a value you're trying to set when the container is running, you want ENV and not ARG. In your Kubernetes manifest, you can change this using a Pod spec's env: setting. (Also Compose environment: or the docker run -e option.)

More specifically in a Helm context, I would recommend making "environment name" a configurable value, rather than pass in an undifferentiated list of command-line arguments or environment values.

Root privileges needed for "systemctl suspend" command

Asked 2021-Oct-06 at 08:05

On an embedded Linux device (Colibri module with an iMX7d processor) I am not able to run the command systemctl suspend as an non-root user in order to switch into suspend mode. When I log in as root user, the command is executed and the system switches to suspend mode. The same command runs on a Ubuntu PC system as an non-root user.

I would like enter the suspend mode also on the embedded Linux device without root privileges. Can anybody help me or show me the direction on how to achieve this? Any help would be greatly appreciated.

Here is the Linux kernel version of the embedded device:

To allow running root only command for other (non-root) users, you can use sudo https://linux.die.net/man/8/sudo

Assuming your non-root user that needs to be able to suspend is called: user1

Create file in /root/suspend.sh that contains systemctl suspend, and make sure it's mode is 0700 and owned by root:root, e.g. run these as root:

Re-posting relevant parts.

Looks like your Ubuntu version is using the "hybrid" cgroup mode by default. Cgroup v2 is indeed enabled in your kernel, but not necessarily in use – in the hybrid mode, systemd still mounts all resource controllers (cpu, memory, etc.) in v1 mode and only sets up its own process tracking in the v2 tree. See findmnt.

You could boot with the systemd.unified_cgroup_hierarchy=1 kernel option to switch everything to cgroups v2, but if you're using container software (docker, podman) make sure those are cgroups v2-compatible.

Even after making these changes MemorySwapMax not taking into effect.

You need to add also swapaccount=1, swap accounting is enabled by default only since kernel v5.8.

Answered 2021-Jun-18 at 15:09

There are actually two problems you are running into. First, it looks like you are specifically using the Ansible systemd module. That's not going to work, since WSL doesn't support systemd without extensive effort.

Since the WSL Ubuntu 20.04 distribution, as you've noticed, does provide a fallback to the service command, you should be able to simply swap that out with the Ansible service module. E.g.:

AWC EC2 Amazon Linux 2 Instances failed to boot after applying os updates

Asked 2020-Oct-30 at 11:21

Yesterday we lost contact with 10 identically configured servers, after some investigation the conclusion was that a reboot after security updates had failed.

We have so far not been able to get any of the servers back online, but were lucky enough to be able to reinstall the instances without data loss.

I will paste the console log below, can anyone help me determine the root cause and perhaps give me some advice on if there is a better way to configure the server to make recovery easier (like getting past the "Press Enter to continue." prompt, that it seems to hang in).

The full log is too big for SO, so I put it on pastebin and pasted a redacted version below. I have removed the escape sequences that colorize the output and removed some double new lines, but besides that it is complete.

Answered 2020-Oct-30 at 11:21

Ok, shortly after posting we figured it out. Seems like a mount point has changed (I expect due to a linux kernel update) and we have not used the nofail option in /etc/fstab as described in the aws knowledge center, this caused the server to hang at boot.

Going forward we will also ensure we use UUID mounting so we are independent on the device naming in /dev/.
