Redmined

A dockerized CLI for the Redmine development environment. Inspired by rails/docked.

Features

• Provides a reproducible Redmine development environment anywhere
• Requires only Redmine source code and Docker
• Supports multiple environments with different Ruby versions, custom ports, and configurable environment variables
• Can be executed from any subdirectory of the Redmine source code

Prerequisites

• Source code of Redmine or its distribution such as RedMica
• Docker

Installation

Download redmined and place it in a location in your PATH, such as ~/.local/bin/, and grant execution permission.

Or, you can install it directly by running the following commands.

wget -qO- https://raw.githubusercontent.com/hidakatsuya/redmined/main/install.sh | sh

Or

curl -sSL https://raw.githubusercontent.com/hidakatsuya/redmined/main/install.sh | sh

Usage

cd your-redmine-root-directory

Create configuration for SQLite database.

cat <<EOS > config/database.yml
development:
  adapter: sqlite3
  database: db/development.sqlite3
test:
  adapter: sqlite3
  database: db/test.sqlite3
EOS

Setup and start Redmine.

redmined bundle install
redmined bin/rails db:prepare
redmined bin/rails s

Run tests.

redmined bin/rails test
redmined bin/rails test:system

Note

Since Chrome is not installed on the ARM64 platform, test:system task can't be executed.

Tip

I recommend you define a short command, such as r, as an alias for redmined command.

Supported Versions

• Redmine: Tested with the latest master branch of redmine/redmine
• Ruby: Supports Ruby 3.2, 3.3, 3.4-rc

Settings

Global settings

• REDMINED_CONTAINER_NAME Container name for redmined. If not set, use "redmined-container" as default.
• REDMINED_MAP_HOST_USER_TO_CONTAINER_USER Map the UID and GID of the host user to the container user
• REDMINED_BUNDLE_CACHE_VOLUME Volume name for bundler cache. If not set, use "redmine-bundle-cache" as default.
• REDMINED_IMAGE Docker image for redmined. If not set, use "ghcr.io/hidakatsuya/redmined" as default.
• REDMINED_RUBY Ruby version for redmined. If set and REDMINED_IMAGE does not contain the image tag, set the image tag to "ruby<REDMINED_RUBY>".
• REDMINED_REDMINE_PORT Port number for Redmine. If not set, use "3000" as default.
• REDMINED_CONTAINER_ENVS Additional environment variables for redmined container. Multiple variables can be set by separating them with a space. If not set, use "" as default.
• REDMINED_PUBLISH_PORT Port mapping for Redmine. If not set, use "3000:3000" as default.
• REDMINED_PLATFORM Platform for the container image redmined uses.
• REDMINED_NO_TTY Whether to run the container in non-TTY mode. If not set, disable non-TTY mode. No TTY mode is also enabled by -T opeion of redmined command.

See redmined for further details.

Individual settings

You can create the configuration file named .redmined.json for different Redmine environments in the Redmine root directory.

{
  "default": {
    "name": "redmine",
    "ruby": "3.3",
    "port": "3000",
    "env": {
      "PUMA_MIN_THREADS": 1
    }
  }
}

Then, you can use Redmine in the above environment by executing the command as usual. The details of the configuration are as follows:

• name: It determines to the following settings
  • REDMINED_BUNDLE_CACHE_VOLUME=redmined-<name>-bundle-cache
  • REDMINED_CONTAINER_NAME=redmined-<name>-container
• image: It determines the container image redmined uses
  • REDMINED_IMAGE=<image>
• ruby: It determines the container image redmined uses
  • REDMINED_IMAGE=REDMINED_IMAGE:ruby<ruby>
• port: It determines the --expose settings of docker run and $PORT which rails server respects
  • REDMINED_REDMINE_PORT=<port>
  • REDMINED_PUBLISH_PORT=<port>:<port>
• env: It determines additional environment variables for the redmined container
  • REDMINED_CONTAINER_ENVS=values of <env>
• platform: It determines the platform of the container image redmined uses
  • REDMINED_PLATFORM=<platform>

Additionally, you can add the configuration for the different Redmine environment.

{
  "default": {
    "name": "redmine",
    "ruby": "3.3"
  },
  "ruby3.2": {
    "name": "redmine-ruby3.2",
    "ruby": "3.2",
    "port": "3001"
  }
}

The environment added above can be used as follows:

redmined -n ruby3.2 bin/rails server

Advanced Usage and Tips

Updating the redmined CLI and the redmined images

You can update the redmined CLI and the redmined images by executing redmined -u.

$ redmined -u
Updating redmined...
Installed redmined to /home/hidakatsuya/.local/bin

Updating redmined images...
ghcr.io/hidakatsuya/redmined:latest
ghcr.io/hidakatsuya/redmined:ruby3.3

Executing with non-TTY mode

You can execute the command with non-TTY mode by using the -T option.

redmined -T bundle install

Or, you can set the environment variable REDMINED_NO_TTY to enable non-TTY mode.

export REDMINED_NO_TTY=1
redmined bundle install

Using separate environments for multiple Redmines

You can configure the indivisual settings for different Redmine environments. See Individual settings for further details.

Developing a Redmine plugin with Redmined CLI

Since Redmined CLI supports running in subdirectories, you can run redmined in plugins/redmine_xxxx/.

This means you can develop a Redmine plugin in the following way.

Suppose your Redmine source code is stored as follow:

/home/you/redmine
  ├── app/
  ├── plugins/
  :

Then, place your Redmine plugin in plugins/redmine_your_plugin and go to that directory.

cd plugins/redmine_your_plugin

You can run commands such as bin/rails s or bin/rails redmine:plugins:test under the plugins directory. You don't need to navigate to the Redmine root directory to run those commands.

pwd
/path/to/redmine/plugins/redmine_your_plugin

redmined bin/rails redmine:plugins:test
redmined bin/rails s

Executing redmined command with modified environment variables

redmined env RAILS_ENV=development bin/about

Resetting the installed gems

The gems installed by redmined bundle install are stored in the docker volume. You can check the name of the docker volume by the following way.

If there is the .redmined.json file in the Redmine root directory, the docker volume name is redmined-bundle-cache-<name of the current configuration>, otherwise, it is redmine-bundle-cache.

After that, you can remove the docker volume by the following command.

docker volume rm <the docker volume name>
