3.3.4 fails to init due to mysql2 gem

[santiagocardin]

After a container restart today our Redmine 3.3.4 with MySQL backend is breaking due to the following error:

current directory: /usr/local/bundle/gems/mysql2-0.4.8/ext/mysql2
/usr/local/bin/ruby -r ./siteconf20170711-7-l14zoc.rb extconf.rb

To see why this extension failed to compile, please check the mkmf.log which can
be found here:

  /usr/local/bundle/extensions/x86_64-linux/2.2.0/mysql2-0.4.8/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /usr/local/bundle/gems/mysql2-0.4.8 for
inspection.
Results logged to
/usr/local/bundle/extensions/x86_64-linux/2.2.0/mysql2-0.4.8/gem_make.out

An error occurred while installing mysql2 (0.4.8), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.4.8'` succeeds before bundling.

In Gemfile:
  mysql2

Redmine 3.3.3 (which uses a different myql2 gem version) still boots properly.

Seems mysql2 0.4.8 gem version has been recently released and is being now used by Redmine ("~> 0.4.6"). A Dockerfile update my be needed to include a new MySQL client dependency.

Same issue happening to me.
This seems to be the same issue reported as #21, but it hasn't been resolved - there's only a workaround and it doesn't work for docker-compose.

[yosifkit]

Any details about how this is deployed so that we can reproduce it? Contents of docker-compose.yml or docker run lines?

I have the same problem when running the latest version of redmine today (given mysql container is properly bootstrapped) :

docker run -d --name redmine --link mysql:mysql -p 3000:3000 redmine

[pmietlicki]

Hi,
Same problem here.

Oh, sorry, I've forgotten to add that. I've used the example that is in the Redmine image's description on DockerHub:

version: '3.1'

services:

  redmine:
    image: redmine
    ports:
      - 8080:3000
    environment:
      REDMINE_DB_MYSQL: db
      REDMINE_DB_PASSWORD: example

  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: redmine

I've put that in a docker-compose.yml and tried to up it. I've also tried doing that for Redmine 3.2 resulting in the same error.

[marouanabbessi]

I build a redmine image from the 3.3 version metadata, and it works fine for me

[santiagocardin]

Building a new 3.3.4 redmine image from the Dockerfile works well. The one uploaded to Dockerhub fails to run due to the mentioned error.

[wefixit-AT]

Can anybody please update the files from Dockerhub, so we can use redmine again

[yosifkit]

Should be fixed by #80. We'll get an update PR to official-images shortly.

[LJBD]

@yosifkit - thanks a lot!
Could you please define "shortly"? Is it a matter of days or weeks?

[yosifkit]

Shortly, as in, it was merged in docker-library/official-images#3194 on 13 July 2017, 4:06 PM PDT and is available on the Docker Hub.

[LJBD]

@yosifkit - all right, thanks again!
I was asking because I've seen the same error yesterday, but it turned out that I haven't configured my MySQL container properly and now everything is fine.

[marouanabbessi]

Thanks for the update ..
