问题 I'm using docker-compose to stand up an Express/React/Mongo app. I can currently stand up everything using retry logic in the express app. However, I would prefer to use Docker's healthcheck to prevent the string of errors when the containers initially spin up. However, when I add a healthcheck in my docker-compose.yml , it hangs for the interval/retry time limit and exits with: ERROR: for collector Container "70e7aae49c64" is unhealthy. ERROR: for server Container "70e7aae49c64" is unhealthy

问题 I am using Docker Desktop with linux containers on Windows 10 and would like to launch the latest versions of the elasticsearch and kibana containers over a docker compose file. Everything works fine when using some older version like 6.2.4. This is the working docker-compose.yml file for 6.2.4. version: '3.1' services: elasticsearch: image: docker.elastic.co/elasticsearch/elasticsearch:6.2.4 container_name: elasticsearch ports: - "9200:9200" volumes: - elasticsearch-data:/usr/share

问题 my redis container is defined as he standard image in my docker_compose.yml redis: image: redis ports: - "6379" I guess it's using standard settings like binding to Redis at localhost I need to bind it to 0.0.0.0, is there anyway to add a local redis.conf file to change the binding and let docker-compose knows it? thanks for any trick... 回答1: Yes. Just mount your redis.conf over the default with a volume: redis: image: redis volumes: - ./redis.conf:/usr/local/etc/redis/redis.conf ports: -

问题 I have the following docker-compose file version: '3' services: node1: build: node1 image: node1 container_name: node1 node2: build: node2 image: node2 container_name: node2 I can build both images and start them with a single command docker-compose up -d --build But I would like to use build-args on the builds. The original build script of the image outside of the scope of compose looks something like this #!/bin/sh docker build \ --build-arg ADMIN_USERNNAME_1=weblogic \ --build-arg ADMIN
