creates a mocked docker environment with persistent and dynamic containers for testing issues
Seeder:
To create a mocked docker environment run dnsdrone/mocker as seeder by using the seed command.
The seeder instance will create the defined amount of persistent containers which will idle infinitely
and the defined amount of dynamic containers which will kill themselves by a random time between the
minimum and maximum lifespan value.
(when a dynamic containers maximum lifespan is reached it will kill itself and the seeder creates a new one with a random idle time to keep up to the defined amount of containers)
docker run --rm -ti \
-v "/var/run/docker.sock:/var/run/docker.sock" \
-e "SPAWN_PERSISTENT=<number>" \
-e "SPAWN_DYNAMIC=<number>" \
-e "SPAWN_MIN_LIFESPAN=<number>" \
-e "SPAWN_MAX_LIFESPAN=<number>" \
-e "MOCKED_LABELS_GLOB=<string>" \
--name "dnsdrone-seeder" \
dnsdrone/mocker \
seedIdler:
You can also create idling instances directly and skip the automatic seeder by running the container
with the idle command to keep an infinite idling container.
(optionally you can add an integer value as a parameter for a desired amount of minutes -
for instance idle 3 for creating a container that will kill itself after three minutes)
docker run --rm -ti \
-v "/var/run/docker.sock:/var/run/docker.sock" \
--name "dnsdrone-idler" \
dnsdrone/mocker \
idle [int minutes]| name | default | description |
|---|---|---|
| SPAWN_PERSISTENT | 10 | amount of persistent idle containers |
| SPAWN_DYNAMIC | 15 | amount of dynamic idle containers |
| SPAWN_MIN_LIFESPAN | 5 | minimum idle time of dynamic containers |
| SPAWN_MAX_LIFESPAN | 10 | maximum idle time of dynamic containers |
| MOCKED_LABELS_GLOB | * | pattern for picking random label files |
You can find an example use case in test_local.sh.
