CLI Commands


CaptainCore is a command line application for automating WordPress maintenance. Only administrators of a CaptainCore instance would run commands directly. Regular users will simply use CaptainCore Manager installed on a WordPress site.

How site names work

CaptainCore uses arbitrary site names. When managing multiple sites, there needs to be a way to uniquely identify each site. While domain names seems like a good option, there are times you may want to be managing the same site with the same domain on multiple host providers. Also domain names can be long and sometimes change. On of flip side using a completely arbitrary site ID isn't very human friendly. A site name is something in between. A short but meaningful name that is unchangeable even if the domain name changes.

Site names can also specify a provider using an @ symbol <site>@<provider>. This makes dealing with multiple host providers enjoyable. Here's an example coping a site between providers captaincore copy anchorhost@wpengine anchorhost@kinsta. Omitting the provider is completely valid however won't be very particular if multiple site names exist.

Targeting sites

Many commands also support targeting many sites. To target use @all, @production or @staging after the command. These can be combined to filter sites further by chaining other modifiers after the target. For example @production.updates-on will target production sites are marked for automatic updates and @all.offload-on will target all sites which have offload enabled.

This allows for flexible repeat process. For example updating themes/plugins on production sites every week with captaincore update @production.updates-on and then monthly on staging sites with captaincore update @staging.updates-on.

Fleet mode

With fleet mode enabled a single CaptainCore instance can support sites for many different GUIs (or known as captains). Each captain only has ability to run commands on their respective sites. Internally this works by passing --captain-id=<captain_id> onto each captaincore <command>. Commands run without a --captain-id will default to ID 1.

Any command can be run across the entire fleet using --fleet. For example running captaincore backup @production --fleet will loop through all CaptainIDs. For a fleet with 3 CaptainIDs that command will run:

  • captaincore backup generate @production --captain-id=1
  • captaincore backup generate @production --captain-id=2
  • captaincore backup generate @production --captain-id=3

Long running commands

Long running tasks like captaincore copy or captaincore move can prematurely end due to SSH idle. In order to help reduce disconnects add the following to ~/.ssh/config which will keep SSH alive by sending a signal every four minutes (240 seconds) to the remote host.

Host *
ServerAliveInterval 240
