QUESTION
I have a problem installing docker on my virtual machine. I have followed the steps below:
1. Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:
sudo apt-get remove docker docker-engine docker.io containerd runc
2. Update the apt package index
sudo apt-get update
3. install packages to allow apt to use a repository over HTTPS:
...ANSWER
Answered 2021-Aug-09 at 12:48Make sure the content of the /etc/apt/sources.list.d/docker.list
corresponds to the output of the command in the documentation, bullet #3.
At the time of this writing executing the command on my Ubuntu 20.04 LTS results in the following content of the docker.list file:
deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu focal stable
which seems to be different from that of yours.
QUESTION
I am running into the following error when starting up containers on my Raspberry Pi 3B on Raspbian Buster:
...ANSWER
Answered 2022-Mar-04 at 17:33I was able to resolve this, unfortunately I won't be able to find out why this happened.
I tried removing and installing docker-ce
and dependencies again. I wasn't able to remove due to containerd.service
not stopping. I found it was set to always restart, which would normally make sense. I then ran sudo systemctl disable docker containerd
and rebooted. I confirmed those services were no longer running by following journalctl output, looking for the usual restarting and core-dump errors from docker
and containerd
.
I ran sudo apt remove docker-ce
and sudo apt autoremove
again, then ran docker's get-docker.sh
which reinstalled docker. I then ran sudo systemctl enable docker containerd
and sudo systemctl start docker containerd
. Docker is the same version it was before and the hello-world container and other containers of mine that wasn't previously running is now running successfully.

Now I want to use jtest
to do a unit test in the typescript (Node version v16.13.2)project, first I install the jtest "jest": "^27.5.1"
. Add jest.config.js
file:
ANSWER
Answered 2022-Mar-04 at 02:27You probably have "type": "module"
in your package.json
file. If you remove that it will fix this.
Alternatively, if you want to keep your "type": "module"
you could convert your jest.config.js
to be jest.config.json
(and/or if you have a babel.config.js
you will need to convert that one to be babel.config.json
as well). Note that you will actually have to convert it to be in JSON format (so, remove module.exports =
from it, etc).
This example project goes way more in depth on all this
QUESTION
I'm fairly new to docker and I'm trying to run some minecraft containers, however they don't seem to be honoring the cpu limits I'm setting. As you can see in the commented out portions, i'v also tried using v3. No matter what limit I set, the container shows up to 400% cpu usage in docker stats. It is a 4cpu virtual machine hosted with Oracle, running Ubuntu.
Is there any other way to enforce this limit?

Answered 2022-Jan-24 at 04:28So I've managed to fix my own issue. I had a thought, and so I did this by removing docker compose v2 (yaml v3) with

I'm trying to setup redmine (with postgres) on my raspberry pi 3 using docker-compose. It already worked once, but then I tried to install plugins and somehow managed to bork my system.
Now it won't let me start my database container anymore. Even creating a new postgres:12.8
container, yields the error layer does not exist

Answered 2021-Aug-16 at 11:05Nuking /var/lib/docker
seems to get the system working again - this removes all images and lots of other docker-related data.
This doesn't feel like a great solution, but it'll have to do for now.
QUESTION
I am trying to use podman inside a docker container, with no intention to run containers. podman will be used only for login, pull and push.
I am using python:3.7-bullseye docker image, and install the following packages:
...ANSWER
Answered 2021-Oct-21 at 01:55A podman login to a private registry as the root user records the authentication under /run/containers/0/auth.json
by default. It will write to ${XDG_RUNTIME_DIR}/containers/auth.json
if the variable is set. Verify that the /run/containers
path exists, is a directory and you have permission to write to it from within the container. Then do the same for ${XDG_RUNTIME_DIR}/containers
if it exists.
My guess is a bind mount of a file on somewhere in one of the paths above is putting a file where podman is expecting a directory to be. This is preventing the application from writing out the auth.json file under that path.
You can also explicitly override the auth file path using export REGISTRY_AUTH_FILE=
. Test a login after setting this to a known writable value.
QUESTION
How do I "FLUSHALL" in redis in this situation?
Running redis via docker on PopOs 21.0.4 as shown in the following docker-compose.yml
...ANSWER
Answered 2021-Nov-11 at 02:20The error message means that Redis is still loading data, i.e. in your case, the AOF file. You cannot run FLUSHALL
until the loading finishes.
If you don't need the data to be loaded, you can delete the AOF file before starting Redis.
QUESTION
So I'm trying to build an Alpine container, including an app that requires bash
and curl
to install.
Trouble is that Alpine seems to think the year is 2037 (possibly because of the host Pi's lack of a hardwareClock) ignoring the correct host OS/system time (kept up-to-date by NTP), so the apk call fails:
...ANSWER
Answered 2021-Oct-23 at 18:32I would answer "How can I install curl and bash at build-time" not "How to set time in Docker container at build time":
I guess apk is failing because repo TLS certificate dl-cdn.alpinelinux.org
is not valid after 2037 = valid TLS connection can be created. You only need to install package, so you may sacrifice TLS security in this case and plain HTTP connectuon to repository can be used as a workaround. E.g.
