Teuthology的使用与Ceph自动化测试用例的编写（二）

Teuthology常用的task

下面列举了一些常用的tasks，还有很多没列出来，可以自己去查看tasks。这也是这个系列的最后一篇了吧，其他，比如代码执行流程之类的，代码比较简单也有什么好写的了，如果有需要可以写一写。

Install

Install packages for a given project.

Install packages for a given project.

    tasks:
    - install:
        project: ceph
        branch: bar
    - install:
        project: samba
        branch: foo
        extra_packages: ['samba']
    - install:
        rhbuild: 1.3.0
        playbook: downstream_setup.yml
        vars:
           yum_repos:
             - url: "http://location.repo"
               name: "ceph_repo"

Overrides are project specific:

    overrides:
      install:
        ceph:
          sha1: ...

Debug packages may optionally be installed:

    overrides:
      install:
        ceph:
          debuginfo: true

Default package lists (which come from packages.yaml) may be overridden:

    overrides:
      install:
        ceph:
          packages:
            deb:
            - ceph-osd
            - ceph-mon
            rpm:
            - ceph-devel
            - rbd-fuse

    When tag, branch and sha1 do not reference the same commit hash, the
    tag takes precedence over the branch and the branch takes precedence
over the sha1.

    When the overrides have a sha1 that is different from the sha1 of
    the project to be installed, it will be a noop if the project has
    a branch or tag, because they take precedence over the sha1. For
instance:

    overrides:
      install:
        ceph:
          sha1: 1234
    tasks:
    - install:
        project: ceph
          sha1: 4567
          branch: foobar # which has sha1 4567

    The override will transform the tasks as follows:
    tasks:
    - install:
        project: ceph
          sha1: 1234
          branch: foobar # which has sha1 4567

    But the branch takes precedence over the sha1 and foobar
    will be installed. The override of the sha1 has no effect.
    When passed 'rhbuild' as a key, it will attempt to install an rh ceph build
using ceph-deploy

    Reminder regarding teuthology-suite side effects:
    The teuthology-suite command always adds the following:
    overrides:
      install:
        ceph:
          sha1: 1234

    where sha1 matches the --ceph argument. For instance if
    teuthology-suite is called with --ceph master, the sha1 will be
    the tip of master. If called with --ceph v0.94.1, the sha1 will be
    the v0.94.1 (as returned by git rev-parse v0.94.1 which is not to
    be confused with git rev-parse v0.94.1^{commit})

Upgrades packages for a given project

Upgrades packages for a given project. example: {cmd_parameter} = ceph_deploy_upgrade 


    For example::
        tasks:
        - install.{cmd_parameter}:
             all:
                branch: end

    or specify specific roles::
        tasks:
        - install.{cmd_parameter}:
             mon.a:
                branch: end
             osd.0:
                branch: other

    or rely on the overrides for the target version::
        overrides:
          install:
            ceph:
              sha1: ...
        tasks:
        - install.{cmd_parameter}:
            all:
    (HACK: the overrides will *only* apply the sha1/branch/tag if those
    keys are not present in the config.)

    It is also possible to attempt to exclude packages from the upgrade set:
        tasks:
        - install.{cmd_parameter}:
            exclude_packages: ['ceph-test', 'ceph-test-dbg']

ceph

Set up and tear down a Ceph cluster

Set up and tear down a Ceph cluster.

    For example::
        tasks:
        - ceph:
        - interactive:

    You can also specify what branch to run::
        tasks:
        - ceph:
            branch: foo

    Or a tag::
        tasks:
        - ceph:
            tag: v0.42.13

    Or a sha1::
        tasks:
        - ceph:
            sha1: 1376a5ab0c89780eab39ffbbe436f6a6092314ed

    Or a local source dir::
        tasks:
        - ceph:
            path: /home/sage/ceph

    To capture code coverage data, use::
        tasks:
        - ceph:
            coverage: true

    To use btrfs, ext4, or xfs on the target's scratch disks, use::
        tasks:
        - ceph:
            fs: xfs
            mkfs_options: [-b,size=65536,-l,logdev=/dev/sdc1]
            mount_options: [nobarrier, inode64]

    Note, this will cause the task to check the /scratch_devs file on each node
    for available devices.  If no such file is found, /dev/sdb will be used.
    To run some daemons under valgrind, include their names
    and the tool/args to use in a valgrind section::

        tasks:
        - ceph:
          valgrind:
            mds.1: --tool=memcheck
            osd.1: [--tool=memcheck, --leak-check=no]

    Those nodes which are using memcheck or valgrind will get
    checked for bad results.
