Development
Adding a server type¶
Adding a new server TYPE
can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:
- Copy an existing "start-deploy*" script, such as start-deployFabric and rename it accordingly making sure to retain the "start-deploy" prefix
- Modify the type-specific behavior between the "start-utils" preamble and the hand-off to
start-setupWorld
at the end of the script - Develop and test the changes using the iterative process described below
- Add a case-entry to the
case "${TYPE^^}"
in start-configuration - Add a section to the docs. It is recommended to copy-modify an existing section to retain a similar wording and level of detail
- Submit a pull request
Iterative script development¶
Individual scripts can be iteratively developed, debugged, and tested using the following procedure.
First, build a baseline of the image to include the packages needed by existing or new scripts:
PowerShell: (Example of building and testing ForgeAPI)
$env:FOLDER_TO_TEST="forgeapimods_projectids"
$env:IMAGE_TO_TEST="mc-dev"
docker build -t $env:IMAGE_TO_TEST .
pushd "tests/setuponlytests/$env:FOLDER_TO_TEST/"
docker-compose run mc
docker-compose down -v --remove-orphans
popd
PowerShell: Building different images of Java for testing
$env:BASE_IMAGE='eclipse-temurin:8u312-b07-jre'
$env:IMAGE_TO_TEST="mc-dev"
docker build --build-arg BASE_IMAGE=$env:BASE_IMAGE -t $env:IMAGE_TO_TEST .
Bash: (Example of building and testing ForgeAPI)
export FOLDER_TO_TEST="forgeapimods_file"
export IMAGE_TO_TEST="mc-dev"
docker build -t $IMAGE_TO_TEST .
pushd tests/setuponlytests/$FOLDER_TO_TEST/
docker-compose run mc
docker-compose down -v --remove-orphans
popd
Using the baseline image, an interactive container can be started to iteratively run the scripts to be developed. By attaching the current workspace directory, you can use the local editor of your choice to iteratively modify scripts while using the container to run them.
From within the container you can run individual scripts via the attached /scripts/
path; however, be sure to set any environment variables expected by the scripts by either export
ing them manually:
...or pre-pending script execution:
Note
You may want to temporarily add an exit
statement near the end of your script to isolate execution to just the script you're developing.
Using development copy of tools¶
In the cloned repo, such as mc-image-helper
, create an up-to-date snapshot build of the tgz distribution using:
Note
The distribution's version will be 0.0.0-<branch>-SNAPSHOT
For Go base tools, run
Clone itzg/github-releases-proxy and run it according to the instructions shown there.
In the Docker build, configure the following
and declare one or more version overrides, such as
Generating release notes¶
The following git command can be used to provide the bulk of release notes content:
shell script
git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="* %s" 1.1.0..1.2.0
