Doozer Development Container Support for VSCode

This directory contains the Dockerfile and devcontainer.json file that allows you to develop and debug doozer inside a development container using Visual Studio Code. See https://code.visualstudio.com/docs/remote/containers for more information.

Quick Start

1. Install the Remote Development Extension Pack on Visual Studio Code.
2. Open doozer project locally.
3. If you are using Linux, make sure the USER_UID USER_GID arguments in dev.Dockerfile match your actual UID and GID. Ignore this step if you are using macOS or Windows.
4. Click the green icon on the bottom left of the VSCode window or press F1, then choose Remote-Containers: Reopen in Container.

Development container use with podman

The same Dockerfile can be used independently to provide a doozer environment container. A build with podman may look like:

podman build --build-arg USERNAME=yours --build-arg USER_UID=1234 \
             -f .devcontainer/dev.Dockerfile -t local/doozer .

Then a script similar to the following (you will certainly want your own modifications) will run the container, mounting in relevant things from your own user directory to be accessible to the same user inside the container.

#!/bin/bash

USER=yours
# location of doozer checkout
DOOZER="$HOME/openshift/doozer"
CONTAINER="$DOOZER/.devcontainer"

# make a copy of your kerberos credentials to mount in (if you mount in the original,
# the selinux labels are changed and kerberos refuses to update it).
cp -a "${KRB5CCNAME#FILE:}"{,_doozer}

# mounting in your .ssh dir changes selinux labels, preventing sshd from logging
# your user in remotely; make a copy and mount that instead if needed.
rm -rf $HOME/.ssh_doozer
cp -a $HOME/.ssh{,_doozer}

# you'll likely have to modify uidmap according to your own user's uid range.
# for 1234 below of course substitute your own UID.
podman run -it --rm \
    --uidmap 0:10000:1000 --uidmap=1234:0:1 \
    -v "${KRB5CCNAME#FILE:}_doozer":/tmp/krb5cc_1234:ro,z \
    -v $DOOZER:/workspaces/doozer:cached,z \
    -v $HOME/.ssh_doozer:/home/$USER/.ssh:ro,cached,z \
    -v $HOME/.gitconfig:/home/$USER/.gitconfig:ro,cached,z \
    -v $CONTAINER/settings.yaml:/home/$USER/.config/doozer/settings.yaml:ro,cached,z \
    -v $CONTAINER/krb5-redhat.conf:/etc/krb5.conf.d/krb5-redhat.conf:ro,cached,z \
