State pip.installed found in sls xxx is unavailable

I’ve been upgrading my Salt cluster which was created a few months ago and left as it was. The problem is happened after sudo do-release-upgrade from Ubuntu 12.04 to 14.04 with salt-master and salt-minions. When I run sudo salt '*' state.highstate, it failed because pip.installed state is unavailable, although pip is installed successfully. After googled I found some related posts.

• 22.26.22.2. Reloading Modules
• Required package not found yet package is installed.
• On first run “State docker.xxx found in sls is unavailable”
• pip.installed state has insufficient pip detection #7659

It’s happened before

As I wrote in this post it’s happened before. At that time I manually removed python-pip packege then re-installed via get-pip.py as a workaround.

$ sudo apt-get remove python-pip
$ wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
$ sudo python get-pip.py

This SLS didn’t work

This SLS file occurs a error. It looks correct at first sight.

/srv/salt/docker/init.sls

...
python-pip:
  pkg.installed

docker-py:
  pip.installed:
    - require:
      - pkg: pkg-core
      - pkg: python-pip

A revised SLS

In found a related Salt Documatation in 22.26.22.2. Reloading Modules. It tells me how to solve this problem using reload_modules flag.

pep8.sls

python-pip:
  cmd:
    - run
    - cwd: /
    - name: easy_install --script-dir=/usr/bin -U pip
    - reload_modules: true

pep8:
  pip.installed
  requires:
    - cmd: python-pip

I revised my SLS as below.

/srv/salt/docker/init.sls

python-pip:
  cmd:
    - run
    - cwd : /
    - name: easy_install --script-dir=/usr/bin -U pip
    - reload_modules: true

docker-py:
  pip.installed:
    - require:
      - pkg: pkg-core
      - cmd: python-pip

After purged old package, it works this time.

$ sudo salt '*' pkg.purge python-pip
$ sudo salt '*' pkg.refresh_db
$ sudo salt '*' state.highstate
