Arranges if and how to restart containers when they exit. Replaces restart.
1. condition: One of none, on-failure or any (default: any).
2. delay: How long to hold up between restarted containers, determined as a length (default: 0).
3. max_attempts: what number occasions to containers to restart a compartment before surrendering (default: never surrender). In the event that the restart does not prevail inside the designed window, this endeavor doesn't tally toward the arranged max_attempts esteem. For instance, if max_attempts is set to '2', and the restart flops on the main endeavor, more than two restarts might be endeavored.
4. window: How long to hold up before choosing if a restart has succeeded, determined as a length (default: choose quickly).
deploy: restart_policy: condition: on-failure delay: 5s max_attempts: 3 window: 120s
Designs how the administration ought to be rollbacked if there should be an occurrence of a coming up short refresh.
1. parallelism: The quantity of holders to rollback at once. Whenever set to 0, all compartments rollback at the same time.
2. delay: an opportunity to hold up between every holder gathering's rollback (default 0s).
3. failure_action: What to do if a rollback comes up short. One of proceed or interruption (default delay)
4. screen: Duration after each errand refresh to screen for disappointment (ns|us|ms|s|m|h) (default 0s).
5. max_failure_ratio: Failure rate to endure amid a rollback (default 0).
6. arrange: Order of tasks amid rollbacks. One of stop-first (old errand is ceased before beginning new one), or begin first (new assignment is begun first, and the running undertakings quickly cover) (default stop-first).
Express reliance between administrations, Service conditions cause the accompanying practices:
1. docker-make up begins benefits in reliance arrange. In the accompanying model, db and redis are begun before web.
2. docker-make up SERVICE naturally incorporates SERVICE's conditions. In the accompanying model, docker-make up web additionally makes and begins db and redis.
3. docker-make stop stops benefits in reliance arrange. In the accompanying precedent, web is ceased before db and redis.
version: '3' services: web: build: . depends_on: - db - redis redis: image: redis db: image: postgres
Override the default entrypoint
Entrypoint may also be a list, in a way similar to dockerfile.
entrypoint: - php - -d - zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so - -d - memory_limit=-1 - vendor/bin/phpunit
Include condition factors from a document. Can be a solitary esteem or a rundown.
On the off chance that you have determined a Compose document with docker-make - f FILE, ways in env_file are in respect to the index that record is in.
Condition factors pronounced in the earth segment abrogate these qualities – this remains constant regardless of whether those qualities are unfilled or vague.
