My objective is to insert one line in a file inside a docker container, sometimes it's working smoothly sometime the docker takes restarts frequently and from the docker logs I am getting this error
-e:5:in <main>': undefined method
[]' for nil:NilClass (NoMethodError)
here is the copy of config/database.yml
development:
adapter: postgresql
database: redmine_test
host: localhost
username: postgres
password: "postgres"
pool: 20 - Added this line
