Example usage:

Sample docker-compose.yml:

version: '3'services:

Then, to guarantee that fusionauth and its dependencies are ready before running proceeding by waiting on a JSON response from fusionauth:9011/api/status:

$ docker-compose run --rm startup_services

You may specify multiple endpoints to wait for JSON response from by seperating them with spaces in the command directive:

startup_services:
image: fusionauth/wait-for-jsondepends_on:
- fusionauthnetworks:
- fusionauthcommand: fusionauth:9011/api/foo fusionauth:9011/api/bar fusionauth:9011/api/baz

start_dependencies:
image: fusionauth/wait-for-jsonenvironment:
- SLEEP_LENGTH: 1
- TIMEOUT_LENGTH: 60
- JSON_TYPE: array

By default, there will be a 2 second sleep time between each check. You can modify this by setting the SLEEP_LENGTH environment variable:

start_dependencies:
image: fusionauth/wait-for-jsonenvironment:
- SLEEP_LENGTH: 0.5

By default, there will be a 300 seconds timeout before cancelling the wait_for. You can modify this by setting the TIMEOUT_LENGTH environment variable:

start_dependencies:
image: fusionauth/wait-for-jsonenvironment:
- SLEEP_LENGTH: 1
- TIMEOUT_LENGTH: 60

By default, we will wait for a JSON object to be returned from the specified endpoints. You can modify this by setting the JSON_TYPE environment variable to one of null, boolean, number, string, array or object:

start_dependencies:
image: fusionauth/wait-for-jsonenvironment:
- SLEEP_LENGTH: 1
- TIMEOUT_LENGTH: 60
- JSON_TYPE: array
