What Patches Do
A patch is a shell script attached to a checkpoint. Patches run in order every time a sandbox is forked from that checkpoint — layer setup without re-creating the checkpoint.
Creating a Patch
From a file or stdin:
# From a file
oc patch create cp-7f3a1b2c --script ./setup.sh --description "Install deps"
# One-liner from stdin
echo "npm install -g typescript" | oc patch create cp-7f3a1b2c --script=-
Layering Setup
Add multiple patches — they execute in creation order on every fork:
oc patch create cp-7f3a1b2c --script ./install-node.sh --description "Node.js 20"
oc patch create cp-7f3a1b2c --script ./app-config.sh --description "App config"
# Each spawned sandbox gets both patches applied in order
oc cp spawn cp-7f3a1b2c
Inspecting Patches
Review what will run before forking:
oc patch list cp-7f3a1b2c
# ID SEQ DESCRIPTION STRATEGY CREATED
# pa-abc123 1 Node.js 20 on_wake 2025-01-15T10:30:00Z
# pa-def456 2 App config on_wake 2025-01-15T10:31:00Z
Removing a Patch
oc patch delete cp-7f3a1b2c pa-abc123
