techdocs-container

This is the Docker container that powers the creation of static documentation sites that are supported by TechDocs.

Getting Started

Using the TechDocs CLI, we can invoke the latest version of techdocs-container via Docker Hub:

npx @techdocs/cli serve

Local Development

docker build . -t mkdocs:local-dev

docker run -w /content -v $(pwd)/mock-docs:/content -p 8000:8000 -it mkdocs:local-dev serve -a 0.0.0.0:8000

Then open up http://localhost:8000 on your local machine.

Release

  1. When you are ready to create a new release head over to releases and click on Draft a new release.

  2. Use an incremental version number for the release e.g. v2.2.1 and use that as the tag version. Github will create a new tag if the tag doesn't exist. Fill out the rest of the fields and click Publish release.

  3. Once released, consider updating the default version used in techdocs-common's TechdocsGenerator.

The release flow is managed by a GitHub actions workflow. Whenever a new release is published on GitHub, the workflow pushes the tag to DockerHub.

Note: The latest tag on DockerHub points to the recent commits in the main branch. This is configured by the main workflow. We recommend using a specific version of the container instead of latest release for stability and avoiding unexpected changes.

Updating PlantUML

PlantUML is a Java based tool which is packaged in a single JAR file. You can find the latest released in their GitHub repo under Releases. When updating the Docker file with a new release of PlantUML you'll need to download the relevant JAR file first and then generate a checksum using sha1sum. Here are the steps:

  1. Download the JAR file: curl -o plantuml.jar -L https://github.com/plantuml/plantuml/releases/download/v1.2024.6/plantuml-1.2024.6.jar
  2. Generate the checksum: sha1sum plantuml.jar
  3. Update the Dockerfile file with the proper release URL and checksum
