Docker container for building devuan iso images using the official devuan-live-sdk.

Basic functionality

The Dockerfile will take a git repo of a blend directory as a template, apply changes to it and commit the result as a new repo.

The container can then be used to build an ISO image based on that new blend.

This ISO should be managed by git LFS by:

.gitattributes:

dist/\*_/_.iso filter=lfs diff=lfs merge=lfs -text

Outline

Put your TEMPLATE_NAME blend under version control or choose someone else's.

GITLAB_URL, TEMPLATE_NAME, BLEND_NAME are ARGS that can be passed to docker build, the passwords should be managed via ssh-agent

NB. You might need docker 19.03 or above with

• { "features": { "buildkit": true } } in /etc/docker/daemon.json
• # syntax = docker/dockerfile:1.2-labs at the top of your Dockerfile
• RUN --mount=type=ssh before any command needing a password

See Dockerfile build enhancement documentation.

Installing with 020_docker.sh will install from docker sources.list and configure these features.

docker build \
    --build-arg GITLAB_URL=git.devuan.org \
    --build-arg TEMPLATE_NAME=devuan-beowulf-live-e17 \
    --build-arg BLEND_NAME=live-zfs-e17

Change the URL for the submodules:

• TEMPLATE_NAME the blend to base the new blend on. DEFAULT devuan-beowulf-live-e17
• BLEND_NAME the new unique blend to create. DEFAULT live-zfs-e17
• GITLAB_URL the repo address for the template and the new blend DEFAULT git.devuan.org

Building

build-with-submodules

Given git credentials, a template name, a blend name and a blend version number for the new blend the docker build will prepare the new containing to build the new devuan iso.

docker build \
  --squash \
  --progress=plain \
  --no-cache \
  --ssh default \
  --build-arg GITLAB_USER="cyteen" \
  --build-arg GITLAB_URL="git.ring-zero.co.uk" \
  --build-arg GITLAB_PORT="10022" \
  --build-arg APT_MIRROR="https://pkgmaster.devuan.org/merged" \
  --build-arg TEMPLATE_NAME="devuan-beowulf-live-e17" \
  --build-arg RELEASE="beowulf" \
  --build-arg BLEND_NAME="live-zfs-e17" \
  --build-arg BLEND_VERS="3.0-test-$(date +%Y-%m-%d)" \
  --build-arg GIT_EMAIL_NAME="cyteen" \
  --build-arg GIT_EMAIL_URL="ring-zero.co.uk" \
  --build-arg GIT_NAME="Cyteen May" \
  -t markm/devuan-live-sdk_sm:latest \
  -t markm/devuan-live-sdk_sm  \
  -f ./Dockerfile-submodule-e17 \
  .

Running

• run.sh - just run the container non-interactively
• run-it.sh - run the container interactively with /bin/zsh

Two stage build

• run-it_sm.sh - first part of the build, interactively:

markm/devuan-live-sdk_sm \
  /bin/zsh -f -c source sdk

• run-it_sm.sh - second part of the build, interactively:

markm/devuan-live-sdk_sm_part2 \
  /bin/zsh -f -c source sdk

Compose

docker-compose.yml and .env
