Configuring alternatives


Infrastructures are often configured in a manner where multiple files providing the same binary exists, and we configure alternatives to set the correct file that should provide the required binary and they are known as alternatives. In this recipe, we will learn how to configure alternatives in Salt.

  1. Create a new state directory called alternatives.

  2. Create and edit the /opt/salt-cookbook/staging/alternatives/init.sls file to have the following entries:

    extract_jdk_archive:
      archive:
        - extracted
        - name: /opt/
        - source: http://reposerver/jdk-7u71-linux-x64.gz
        - source_hash: md5=22761b214b1505f1a9671b124b0f44f4
        - archive_format: tar
        - if_missing: /opt/jdk1.7.0_71
    
    /opt/java:
      file.symlink:
        - target: jdk1.7.0_71
        - require:...
