Troubleshooting runners

Checking the status of a runner

The runner status can be checked on the Runners page associated with the workspace or repository.

  • To find the status of a workspace runner, select Settings on the left sidebar of the workspace, and select Workspace runners under Pipelines on the left sidebar navigation.

  • To find the status of a repository runner, select Repository settings on the left sidebar of the repository, and select Runners under Pipelines on the left sidebar navigation.

The status can be one of the following:

  • Unregistered: The runner was created but was never run. Note: If a runner isn’t registered within one week, it will be removed.

  • Online: The runner is live and available for step scheduling.

  • Offline: The runner is not available. It may have been stopped, or there may be network connectivity issues.

  • Disabled: The runner was temporarily disabled, and steps will not be scheduled on it until it is enabled again.

Reviewing runner logs

Runner logs are located in /<runner_working_directory>/<runnerUuid>/runner*.log.

By default, the working directory is /tmp and the logs are located in /tmp/<runnerUuid>/runner*.log but you can change the working directory of your runner.

Build and services logs for a step are removed from a runner host, but can be found in the step logs on the Pipeline's user interface.

Updating a runner version

If you experience an issue with a runner, update the runner to the latest version.

  1. Stop the runner.

  2. Pull the latest runner version using the command below:

1 docker image pull docker-public.packages.atlassian.com/sox/atlassian/bitbucket-pipelines-runner:1

3. Restart the runner.

Troubleshooting errors when starting a runner

An error message

Solution

docker: Error response from daemon: Conflict. The container name "/runner-76b247e7-b925-5e7b-9da2-1cda14c4ff2c" is already in use by container "c3403236e3af5962ed3a9b8771561bd2021974941cc8a89a40c6c66cecb18f53". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.

Run the command docker container rm -f <runner-name>. Replace the placeholder <runner-name> with the actual name.
For example, for the error message used in this example, you would run docker container rm -f runner-76b247e7-b925-5e7b-9da2-1cda14c4ff2c command.

The installed Docker client must be at least version 19

To install a required version of the docker engine, refer to Install Docker Engine help.

No access to containers directory

Run the following command to add read permissions to the current user:
sudo chmod +r /var/lib/docker/containers

user-ns remapping not allowed in docker settings.

User-ns remapping is not supported. Change the docker daemon configuration. Refer to the following docker docs for more information: Isolate containers with a user namespace.Isolate containers with a user namespace Isolate containers with a user namespace

The docker logging driver must be json-file.

Refer to docker docs to configure a logging driver.

failed to start daemon: error initializing graphdriver: overlay2: the backing xfs filesystem is formatted without d_type support, which leads to incorrect behavior. Reformat the filesystem with ftype=1 to enable d_type support. Backing filesystems without d_type support are not supported.

Refers to docker docs - use the OverlayFS storage driver.

Troubleshooting errors during step execution

An error message

Step execution stage

Solution

Cloning into ... fatal: unable to access ... : SSL certificate problem: self signed certificate in certificate chain

Cloning

Disable SSL verification on git clone in bitbucket-pipelines.yml

bash: ls: command not found (or any standard bash command)

Building

The command not found error mostly occurs when the PATH environment variable is configured as Workspace/Repository/Deployment variable. The default PATH where the binaries exist get overridden with the user-supplied PATH variable which is causing the error to appear in the build.
