Can you define optional docker-compose services? -


is there way define docker compose service such brought up when explicitly request it?

that say:

docker-compose

would not start it, but

docker-compose optional_service

would.

one way achieve define optional service in different compose file. start optional service, run:

$ docker-compose -f docker-compose.yaml -f optional-service.yaml

for example, if have docker-compose.yaml file looks like:

version: '2.1' services:   lb:     image: nginx:1.13              db:     image: redis:3.2.9

i can extend optional-service.yaml looks like:

version: '2.1' services:   busy:     image: busybox

notice both compose files must use same compose file version.

you can read more in compose documentation.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
