Overcast is alpha — behaviour and APIs may change between releases. Pin your version and read the changelog before upgrading.

overcast

Checking a running daemon

overcast status, wait, services and config: is the daemon up, is it ready yet, which services are enabled, and what configuration did it actually resolve.

Four read-only commands against --endpoint: status for a one-line answer, wait for a script that has to block, services for what is enabled, and config for what the daemon resolved.

overcast status
overcast wait --timeout 30s

Part of the CLI reference.

overcast status

Pings /_overcast/health and prints one line — reachability, version, storage backend. When the local instance registry is not empty it also prints a table of every instance overcast start knows about — name, backend, endpoint and lifecycle state — whichever one --endpoint pointed at.

overcast status
overcast status --endpoint http://localhost:4570

overcast wait

Blocks until the daemon at --endpoint reports healthy, then exits 0. This is what a CI job runs after starting overcast serve in the background, before the first AWS call; status checks once and returns.

FlagDefaultDescription
--timeout60sGive up waiting after this long.
--interval500msHow often to poll the health endpoint.
--quietfalsePrint nothing on success.
overcast wait --timeout 30s

overcast services

Lists the AWS services the daemon has enabled and the runtime emulation tier of each — full, partial, inert or stub, explained in Reference index § Runtime emulation tiers.

FlagDefaultDescription
--outputtexttext (aligned table) or json.
overcast services
overcast services --output json | jq '.services[] | select(.tier=="stub")'

overcast config

Prints the running daemon’s effective configuration.

Important

The daemon has to have been started with OVERCAST_DEBUG=true. Without it the command returns an error naming the variable rather than a bare 404.

FlagDefaultDescription
--outputprettypretty (indented) or json (exactly what the daemon sent).
OVERCAST_DEBUG=true overcast serve &
