Saltstack: can I use file.manage to source a file created by another salt state?

noob saltstack question

I have a file that is created in a salt state (a war file) and I want to copy that file to the server's deploy directory when it changes. I was thinking file.managed would be the right approach, so something like:

/var/lib/tomcat7/webapps/app.war:
  file.managed:
    - source: /home/user/project/build/release/app.war
    - user: tomcat7
    - group: tomcat7

The file is built via a separate state, which seems to be running properly.

When salt exec's state.highstate, the output is "Unable to determine upstream hash of source file /home/user/project/build/release/app.war"

Is there a better way to do this? Build a file in one state (so it is local) and then update a target when the built file changes? Thanks for any advice.

Solution

  • You need to change that to a file.copy instead, as file.managed is for fetching files over from the salt master or HTTP/FTP servers.

    /var/lib/tomcat7/webapps/app.war:
  file.copy:
    - source: /home/user/project/build/release/app.war
    - force: True
    - user: tomcat7
    - group: tomcat7
    - require:
      - cmd: the_build_state

    As for linking it to the build, you need to use require, as in the modified state above, which assumes that your build state is defined like this:

    the_build_state:
  - cmd.run:
    ...
