/usr/bin/etcd-defrag

etcd-defrag is a Go command-line tool that defragments etcd members one at a time. It is easier to use and smarter than 'etcdctl defrag'. It connects to etcd endpoints over gRPC, with optional TLS and username/password auth, and can find all cluster members with --cluster or through DNS SRV discovery. Before it starts, it runs health checks on the endpoints. It can also run compaction first, skip a member unless a rule such as 'dbQuotaUsage > 0.8 || dbSizeFree > 200*1024*1024' evaluates to true, move lea…

Usage:
  etcd-defrag [flags]

Flags:
      --auto-disalarm                        automatically disalarm NOSPACE alarms after successful defragmentation
      --cacert string                        verify certificates of TLS-enabled secure servers using this CA bundle
      --cert string                          identify secure client using this TLS certificate file
      --cluster                              use all endpoints from the cluster member list
      --command-timeout duration             command timeout (excluding dial timeout) (default 30s)
      --compaction                           whether execute compaction before the defragmentation (defaults to true) (default true)
      --continue-on-error                    whether continue to defragment next endpoint if current one fails (default true)
      --defrag-rule string                   defragmentation rule (etcd-defrag will run defragmentation if the rule is empty or it is evaluated to true)
      --dial-timeout duration                dial timeout for client connections (default 2s)
      --disalarm-threshold float             threshold ratio for automatic alarm clearing (db size / quota) (default 0.9)
  -d, --discovery-srv string                 domain name to query for SRV records describing cluster endpoints
      --discovery-srv-name string            service name to query when using DNS discovery
      --dry-run                              evaluate whether or not endpoints require defragmentation, but don't actually perform it
      --endpoints strings                    comma separated etcd endpoints (default [127.0.0.1:2379])
      --etcd-storage-quota-bytes int         etcd storage quota in bytes (the value passed to etcd instance by flag --quota-backend-bytes) (default 2147483648)
      --exclude-localhost                    whether to exclude localhost endpoints
  -h, --help                                 help for etcd-defrag
      --insecure-discovery                   accept insecure SRV records describing cluster endpoints (default true)
      --insecure-skip-tls-verify             skip server certificate verification (CAUTION: this option should be enabled only for testing purposes)
      --insecure-transport                   disable transport security for client connections (default true)
      --keepalive-time duration              keepalive time for client connections (default 2s)
      --keepalive-timeout duration           keepalive timeout for client connections (default 6s)
      --key string                           identify secure client using this TLS key file
      --move-leader                          whether to move the leadership before performing defragmentation on the leader
      --password string                      password for authentication (if this option is used, --user option shouldn't include password)
      --skip-healthcheck-cluster-endpoints   skip cluster endpoint discovery during health check and only check the endpoints provided via --endpoints
      --user string                          username[:password] for authentication (prompt if password is not supplied)
      --version                              print the version and exit
      --wait-between-defrags duration        wait time between consecutive defragmentation runs or after a leader movement (if --move-leader is enabled). Defaults to 0s (no wait)
