  Note

  MicroShift logs can be accessed separately from etcd logs using the journalctl -u microshift command.

Procedure

• To display the base database version information, run the following command:

  $ microshift-etcd version

  Copy to Clipboard Toggle word wrap

  Example output

  microshift-etcd Version: 4.17.1
  Base etcd Version: 3.5.13

• To display the full database version information, run the following command:

  $ microshift-etcd version -o json

  Example output

  {
    "major": "4",
    "minor": "16",
    "gitVersion": "4.17.1~rc.1",
    "gitCommit": "140777711962eb4e0b765c39dfd325fb0abb3622",
    "gitTreeState": "clean",

    "goVersion": "go1.21.9"
    "compiler": "gc",
    "platform": "linux/amd64",
    "patch": "",
    "etcdVersion": "3.5.13"
  }

Procedure

• Edit the /etc/microshift/config.yaml file to set the memoryLimitMB value.

  etcd:
    memoryLimitMB: 128

  Copy to Clipboard Toggle word wrap
  Note

  The minimum required value for memoryLimitMB on MicroShift is 128 MB. Values close to the minimum value are more likely to impact etcd performance. The lower the limit, the longer etcd takes to respond to queries. If the limit is too low or the etcd usage is high, queries time out.
