Use python-tempestconf with a profile.yaml file

A profile.yaml is helpful mainly in jobs running on different versions of OpenStack, because arguments for python-tempestconf may differ in each OpenStack version. Using the --profile argument those jobs can use a profile.yaml file for each OpenStack version which makes the code of those jobs much clearer and more readable, as for example they contain less if else statements, …

Note

Apart from --deployer-input config file which specifies content of a tempest.conf, profile.yaml file defines arguments which are passed to python-tempestconf, see CLI documentation.

Warning

If this argument is used, other arguments cannot be defined, it means, user uses either CLI arguments or profile.yaml file.

Note

The generated sample of a profile.yaml file contains all python-tempestconf arguments set to their default values. That means, that you can remove arguments you didn’t modify to keep the file simple and more readable.

python-tempestconf accepts both of the following inputs, so you can use what suits you better, either strings or lists:

create: True
out: ./etc/tempest.conf
deployer-input: ./deploy.txt
no-default-deployer: False
overrides:
  identity.username: my_override
  identity.password: my_password
  network-feature-enabled.api_extensions: all
  volume-feature-enabled.api_extensions: dvr,mine
remove:
  auth.identity: username
  network-feature-enabled.api_extensions: ''
  volume-feature-enabled.api_extensions: dvr,mine

create: True
out: ./etc/tempest.conf
deployer-input: ./deploy.txt
no-default-deployer: False
overrides:
  identity.username: my_override
  identity.password:
    - my_password
  network-feature-enabled.api_extensions:
    - all
  volume-feature-enabled.api_extensions:
    - dvr
    - mine
remove:
  auth.identity: username
  network-feature-enabled.api_extensions:
    - ''
  volume-feature-enabled.api_extensions:
    - dvr
    - mine

Using profile.yaml file

After you’ve created your customized profile.yaml file, let’s say in ./etc/profile.yaml, use it as follows:

$ discover-tempest-config --profile ./etc/profile.yaml
