Can't connect to local MySQL server through socket in bitbucket pipelines

[saurabh pathak]

My bitbucket-pipelines.yml file is showing a error :"_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")".

pipelines: 
  default: 
    - step: 
        image: python:3.5.2
        services:
         - database
        script:
          - pip install -r requirements.txt
          - python manage.py run_test
definitions: 
  services: 
    database:
      image: mysql
      environment: 
        MYSQL_DATABASE: 'pipelines'
        MYSQL_ROOT_PASSWORD: 'let_me_in'
        

Above is my code.Thanks in advance

I ran into this problem. For me the fix was to use '0.0.0.0' instead of 'localhost' in Django as the database HOST. The Atlassian docs clearly state to use localhost, so I believe they are wrong.

[Florian Flock]

Yes, this is definitely a the fix. Maybe they are wrong in the docker network setup of the pipeline.

This resolved my problems too. Thank you!

[Abhishek_Jakhotiya]

This worked for me too! Atlassian should really fix their docs

The usual reasons for that error are that MySQL is not running, or it is configured with a different socket file.  Check your my.cnf for it.
