Fail To Install Plugin In Bitnami Redmine Docker Image

by ADMIN 55 views

Introduction

When trying to install a plugin in the Bitnami Redmine docker image, the container exits with a debug message. The issue arises when the plugin requires additional gems, specifically the json gem, which fails to install due to a lack of development tools. In this article, we will explore the issue, its causes, and possible solutions.

The Problem

When trying to install the plugin using the Bitnami Redmine docker image (latest Redmine 6.0.4), the container exits with the following debug info:

redmine 15:06:34.68 INFO  ==> Executing database migrations
redmine 15:06:34.69 DEBUG ==> Generating secret tokens
bundler: failed to load command: rake (/opt/bitnami/redmine/vendor/bundle/ruby/3.3.0/bin/rake)
/opt/bitnami/ruby/lib/ruby/gems/3.3.0/gems/bundler-2.6.3/lib/bundler/definition.rb:454:in `ensure_equivalent_gemfile_and_lockfile': The dependencies in your gemfile changed, but the lockfile can't be updated because frozen mode is set (Bundler::ProductionError)

This error message indicates that the bundler gem is unable to load the rake command due to a change in the Gemfile dependencies. The error message also mentions that the json gem is required by the oauth2 gem, which is a dependency of the plugin.

The Cause

The cause of the issue is the lack of development tools in the Bitnami Redmine docker image. The json gem requires the json library to be installed, which is not present in the image. As a result, the json gem fails to install, and the bundler gem is unable to load the rake command.

The Solution

To resolve the issue, you need to install the development tools in the Bitnami Redmine docker image. You can do this by running the following command:

apt-get update && apt-get install -y build-essential

This command will install the necessary development tools, including the json library.

Installing the Plugin Manually

If you want to install the plugin manually, you can follow these steps:

  1. Clone the plugin repository using git:
git clone https://github.com/kontron/redmine_oauth.git
  1. Change into the plugin directory:
cd redmine_oauth
  1. Run bundle install to install the required gems:
bundle install
  1. Run rake to install the plugin:
rake

Conclusion

In conclusion, the issue of failing to install a plugin in the Bitnami Redmine docker image is caused by the lack of development tools in the image. To resolve the issue, you need to install the development tools using apt-get. Alternatively, you can install the plugin manually by cloning the repository, running bundle install, and then running rake.
