Log Roles

add-fileserver

Add a remote fileserver to the inventory so that content can be uploaded in subsequent tasks or roles.

Role Variables

fileserver

Complex argument which contains the information about the remote destination as well as the authentication information needed. It is expected that this argument comes from a Secret

Example:

- secret:
    name: site_logs
      data:
        fqdn: logs.example.org
        path: /srv/static/logs
        ssh_known_hosts: |
          logs.example.org ssh-rsa ...
        ssh_username: zuul
        ssh_private_key: !encrypted/pkcs1-oaep
          - ...

fileserver.fqdn

The FQDN of the remote host.

fileserver.path

The remote path. Content will be put into a directory below this path that matches zuul.project.short_name. The full path including the project short name will be added to the hostvars of the host as zuul_fileserver_project_path.

fileserver.ssh_known_hosts

String containing known host signature for the remote host.

fileserver.ssh_private_key

Contents of the ssh private key to use.

fileserver.ssh_username
Default: ansible_user

Remote ssh user name to use.

fileserver_leading_path

This is an optional variable that will be inserted between the base of the path (provided by the path variable) and the zuul.project.short_name final path element.

ara-report

If ARA is enabled, generates a report or saves a copy of the ARA database.

Role Variables

ara_report_run
Default: ``true``

Whether to run this role or not. Possible values:

• true (always run)

• false (never run)

• failure (only run when there has been a failure)

ara_database_path
Default: ``{{ zuul.executor.work_root }}/.ara/ansible.sqlite``

Absolute path where the ARA database is expected on the control node. This should be where the ansible-playbook execution had ARA save the host, task and result data if you provided a custom location through ARA_DATABASE or an ansible.cfg file.

ara_report_type
Default: ``html``

Possible values:

• html

• database

html will have ARA generate and save a statically generated HTML report inside ara_report_path.

database will only save the raw ARA sqlite database inside ara_report_path. The database can then be downloaded by users or loaded dynamically by the ara-wsgi-sqlite middleware.

See the ARA documentation for details.

ara_compress_html
Default: ``true``

When report_type is ‘html’, whether to compress the ARA HTML output or not.

Tip

Make sure the web server is configured to set the required mimetypes in order to serve gzipped content properly.

ara_report_path
Default: ``ara``

This path is relative to the root of the log directory.

When report_type is ‘html’ directory where the HTML report will be generated. When report_type is ‘database’, directory where the database is saved.

ara_report_executable
Default: ``ara``

Path to ara executable.

ensure-output-dirs

Ensure output directories are in place

Role Variables

zuul_output_dir
Default: {{ ansible_user_dir }}/zuul-output

Base directory for collecting job output.

fetch-output

Collect output from build nodes

This role collects logs, artifacts and docs from subdirs of the zuul_output_dir on the remote nodes to equivalent directories on the executor so that later parts of the system can publish the content to appropriate permanent locations.

Note

Log content for multi-node jobs will be put into subdirectories based on remote node name. It is expected that artifacts and docs produced be inherently unique regardless of which build node they were produced on, so all artifacts and docs are pulled back to the same artifacts and docs directory.

Role Variables

zuul_output_dir
Default: {{ ansible_user_dir }}/zuul-output

Base directory for collecting job output.

generate-zuul-manifest

Generate a Zuul manifest file for log uploading

This generates a manifest file in preparation for uploading along with logs. The Zuul web interface can fetch this file in order to display logs from a build.

Role Variables

generate_zuul_manifest_root
Default: {{ zuul.executor.log_root }}

The root directory to index.

generate_zuul_manifest_filename
Default: zuul-manifest.json

The name of the manifest file.

generate_zuul_manifest_output
Default: {{ zuul.executor.log_root }}/{{ generate_zuul_manifest_filename }}

The path to the output manifest file.

generate_zuul_manifest_type
Default: zuul_manifest

The artifact type to return to Zuul.

htmlify-logs

HTMLify text logs

This makes an HTML version of every file in the executor log directory with a .txt or .txt.gz extension. If the original was gzipped, the HTML version will be as well.

merge-output-to-logs

Put artifacts and docs into the executor log dir

Note

This role only works in a trusted context. It is intended to be used in the post playbook of a base job.

This role moves artifacts and docs into the logs dir when zuul.change is defined so that they can be uploaded to the log server for developer preview and validation.

Artifacts and docs are left in place when zuul.change is not defined so that normal publication jobs can publish them to final locations.

publish-artifacts-to-fileserver

Publish contents of {{ zuul.executor.work_root }}/artifacts/ dir using rsync over ssh to a remote fileserver that has previously been added to the inventory by add-fileserver.

Role Variables

add-fileserver sets the following variable in the hostvars of the hosts it adds, but it is documented for reference.

zuul_fileserver_project_path

The remote path. Content will be put into a directory below this path that matches zuul.project.short_name. The full path including the project short name will be added to the hostvars of the host as zuul_fileserver_project_path.

set-zuul-log-path-fact

Sets a fact named zuul_log_path from zuul variables

upload-logs

Upload logs to a static webserver

This uploads logs to a static server using SSH. The server must have been previously added to the inventory; this can be done with the add-fileserver role; see that role’s documentation for a description of the site_logs secret in this example post-run playbook:

- hosts: localhost
  roles:
    - role: add-fileserver
      fileserver: "{{ site_logs }}"

- hosts: "{{ site_logs.fqdn }}"
  gather_facts: False
  roles:
    - role: upload-logs
      zuul_log_url: "http://logs.example.org"

Role Variables

zuul_log_url

Base URL where logs are to be found.

zuul_logserver_root
Default: /srv/static/logs

The root path to the logs on the logserver.

zuul_log_verbose
Default: false

The synchronize task in this role outputs a lot of information. By default, no_log is set to avoid overwhelming a reader of the logs. Set this to true to disable that behavior if it becomes necessary to debug this role.

zuul_site_upload_logs
Default: true

Controls when logs are uploaded. true, the default, means always upload logs. false means never upload logs. ‘failure’ means to only upload logs when the job has failed.

Note

Intended to be set by admins via site-variables.

upload-logs-swift

Upload logs to a swift container

This uploads logs to an OpenStack Object Store (Swift) container.

Role Variables

zuul_site_upload_logs
Default: true

Controls when logs are uploaded. true, the default, means always upload logs. false means never upload logs. ‘failure’ means to only upload logs when the job has failed.

Note

Intended to be set by admins via site-variables.

zuul_log_cloud_config

Complex argument which contains the cloud configuration in os-cloud-config (clouds.yaml) format. It is expected that this argument comes from a Secret.

zuul_log_partition
Default: false

If set to true, then the first component of the log path will be removed from the object name and added to the container name, so that logs for different changes are distributed across a large number of containers.

zuul_log_container
Default: logs

This role will create containers which do not already exist. If partitioning is not enabled, this is the name of the container which will be used. If partitioning is enabled, then this will be used as the prefix for the container name which will be separated from the partition name by an underscore. For example, “logs_42” would be the container name for partition 42.

zuul_log_container_public
Default: true

If the container is created, should it be created with global read ACLs. If the container already exists, it will not be modified.

zuul_log_delete_after
Default: 15552000

Number of seconds to delete objects after upload. Default is 6 months (15552000 seconds) and if set to 0 X-Delete-After will not be set.

zuul_log_path
Default: Generated by the role `set-zuul-log-path-fact`

Prepend this path to the object names when uploading.

zuul_log_create_indexes
Default: true

Whether to create index.html files with directory indexes. If set to false, Swift containers can be marked with a Web-Listings=true property to activate Swift’s own directory indexing.
