Running Container

Run the container in detached mode and always load on boot:

docker run \
    --name devtools \                               # Assign a name to the container
    --detach \                                      # Run container in background and print container ID (or -d)
    --restart unless-stopped \                      # Restart policy to apply when a container exits (default "no")
    --tty \                                         # Allocate a pseudo-TTY (or -t)
    --volume '/etc/localtime':/etc/localtime:ro \   # map your timezone
    --volume '/etc/timezone':/etc/timezone:ro \     # map your timezone
    --volume '/mnt/c/Users/asdf/asdf':/data \       # mount a volume (or -v)
    --volume '/mnt/c/Users/zxcv/qwer':/data \       # mount a volume (or -v)
    --volume "${HOME}/.ssh":/root/.ssh \            # map your SSH key for git pulls
    elfreako/devtools

TIP: you can add your local SSH file to push/pull repos more easily by appending another volume: --volume "${HOME}/.ssh":/root/.ssh \

Connect to container via ZSH:

docker exec -it devtools /bin/zsh

# -i = Keep STDIN open even if not attached
# -t = Allocate a pseudo-TTY

Disabled Git refresh for performance gain: ohmyzsh/ohmyzsh#3288 git config --global --add oh-my-zsh.hide-info 1

VSCode

Recommended usage when flipping between computers is using Settings Sync within VSCode: https://code.visualstudio.com/docs/editor/settings-sync

The Docker extension also allows you to attach the running container as a shell: https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker

v1.0.0: Added /root/.vscode-server folder to map volume locally to speed up extensions being installed/re-used. Add another volume mount: https://code.visualstudio.com/docs/remote/containers-advanced#_avoiding-extension-reinstalls-on-container-rebuild

-v "${HOME}/someFolder/.vscode-server":/root/.vscode-server

WSL

Enabling container dropdown in Windows Terminal using WSL and Docker Desktop: Add a new profile in settings.json under {}profiles.[]list

    {
        "commandline": "docker exec -it devtools /bin/zsh",
        "icon": "E:\\Downloads\\asdf\\qwer\\zxcv\\clover 2.png",
        "name": "Docker devtools",
        "tabColor": "#B018ED",
        "tabTitle": "Docker devtools"
    }

Docker with WSL tends to eat up memory at times, to restrict it, perform the following...

Turn off all WSL instances including docker-desktop:

wsl --shutdown
notepad "$env:USERPROFILE/.wslconfig"

Edit .wslconfig file with notepad, adding these settings:

[wsl2]
memory=3GB   # Limits VM memory in WSL 2 up to 3GB
processors=4 # Makes the WSL 2 VM use two virtual processors

...restart WSL

MacOS Terminal

To enable auto load in MacOS Terminal, edit your Preferences and create/duplicate a Profile. Under the Shell menu of the profile, add docker exec -it devtools /bin/zsh inside the Run Command.
