Why does the sensu-client not start in docker on Travis?

  • 772

This Ansible role has been created and this .travis.yml has been used as an example in order to test the role. All services were able to start, except the sensu-client.

Attempts to solve the issue

In order to solve the issue a debug step was added to travis. When the build completed the following error was thrown:

The command "sudo docker exec "$(cat ${container_id})" ansible-playbook /etc/ansible/roles/role_under_test/tests/test-${SITE}.yml | grep -q 'changed=0.*failed=0' && (echo 'Idempotence test: pass' && exit 0) || (echo 'Idempotence test: fail' && exit 1)

" exited with 1.

When the ansible role is deployed on a remote system the sensu-client starts, but it fails on Travis although the other services are able to start.

systemd sensu travis-ci

    Concise

    The initscripts package was missing. This was found after comparing the files that reside in /etc/init.d on a local system with the ones that reside in the docker container used by Travis. After querying for /etc/init.d/functions it became clear what package had to be installed.

    Verbose

    It seems that files are missing in /etc/init.d, i.e.:

    Aug 08 00:18:19 c6354976113c sensu-client[1534]: /etc/init.d/sensu-service: 
line 71: /etc/init.d/functions: No such file or directory

    Is that true? In order to check that another debug step was added: ls /etc/init.d. The outcome is as follows:

    $ sudo docker exec --tty "$(cat ${container_id})" env TERM=xterm ls /etc/init.d

README  sensu-api  sensu-client  sensu-server  sensu-service  uchiwa

    functions is indeed missing. This post indicated that initscripts needs to be installed. When this package was added to the Dockerfile and the build ran again it succeeded.
