Red Hat build of MicroShift

Examples of configuration snippet lists or arrays

Lists and arrays in {product-title} configuration snippets are overwritten, not merged.

For example, you can replace a SAN or list of SANs by creating an additional snippet for the same field that is read after the first:

MicroShift configuration directory contents: /etc/microshift/config.yaml.default or /etc/microshift/config.yaml
Example MicroShift configuration snippet directory contents: /etc/microshift/config.d/10-san.yaml and /etc/microshift/config.d/20-san.yaml

Example 10-san.yaml snippet

apiServer:
  subjectAltNames:
    - host1
    - host2

Example 20-san.yaml snippet

apiServer:
  subjectAltNames:
    - hostZ

Example configuration result

apiServer:
  subjectAltNames:
    - hostZ

If you want to add a value to an existing list, you can add it to an existing snippet. For example, to add hostZ to an existing list of SANs, edit the snippet you have instead of creating a new one:

Example 10-san.yaml snippet

apiServer:
  subjectAltNames:
    - host1
    - host2
    - hostZ

Example configuration result

apiServer:
  subjectAltNames:
    - host1
    - host2
    - hostZ
