Docker arch testing environment

Instructions to create simple, ready for testing container with archlinux in it to do some experiments on fresh install

Base image: https://hub.docker.com/_/archlinux/

Commands

Get/update image:

docker pull archlinux:multilib-devel

Run container once:

docker run -itv "/host/directory/to/mount:/container/directory/to/mount" --rm archlinux:multilib-devel

Create named container:

Here, replace the %name% with your desired name

docker create -itv "/host/directory/to/mount:/container/directory/to/mount" --name %name% archlinux:multilib-devel

Start the container:

You can use container id if you have not specified name for it

docker start -ai %name%

Build image with root account for packages installation

This can be either done manually using container, created by official archlinux image, or you can create your own image, based on it

In this example, replace %user% with your desired username and %password% with your password:

FROM archlinux:multilib-devel AS runner

# uncomment wheel group to make new user root
RUN sed -i 's/^# %wheel/%wheel/' /etc/sudoers

# update packages
RUN sudo pacman -Syuu --noconfirm

# install dev packages
RUN sudo pacman -S --noconfirm --needed git base-devel

# add new user
RUN useradd -rms /bin/bash -g root -G wheel -p "$(openssl passwd -6 %password%)" %user%
USER %user%
WORKDIR /home/%user%

ENTRYPOINT ["/bin/bash"]

Building the image:

Replace the %image_name% with your desired name:

docker build . -t %image_name%:latest

Sending commits

In case you have your git info in ~/.config/git, it will be overriden the moment you open vscode with ~/.gitconfig. Remove this file before commiting

Custom gitlab

You can create your custom gitlab container with these two simple lines:

docker volume create gitlab-data
docker run --detach --hostname localhost --publish 8443:443 --publish 8080:80 --publish 2222:22 --name gitlab --restart always --volume gitlab-data:/var/opt/gitlab gitlab/gitlab-ce:latest

It will run on your local address with port 8080 (e.g. http://192.168.11.144:8080/). Log in with default root password and create users. You can commit to this server using ssh by creating a new ssh public key and editing ~/.ssh/config, e.g.:

Host gitlab
  HostName 192.168.11.144
  User gigas
  Port 2222
  IdentityFile ~/.ssh/id_ed25519
  IdentitiesOnly yes

The container is also updatable, so you can always do docker pull gitlab-ce:latest before running a new entry
