docker-compose

问题 I use Docker multi-stage build, specifically: Use an external image as a “stage” When using multi-stage builds, you are not limited to copying from stages you created earlier in your Dockerfile. You can use the COPY --from instruction to copy from a separate image, either using the local image name, a tag available locally or on a Docker registry, or a tag ID. The Docker client pulls the image if necessary and copies the artifact from there. The syntax is: In my case I have three Docker files

问题 I added RUN go get to install packages during "docker-compose". However, the following cannot find package error was occurred when I run go build . I found that the packages are saved in /go/pkg/linux_amd64/ . run docker-compose and go build $ docker-compose up -d $ docker exec -it explorer-cli /bin/bash # pwd /go # ls bin pkg src # echo $GOPATH /go # ls /go/pkg/linux_amd64/github.com/ go-sql-driver # go build -i -o /go/bin/explorer-cli src/main.go src/main.go:6:2: cannot find package "github

问题 I use this to set up nginx for PHP: nginx: image: nginx:latest ports: - 8080:80 volumes: - ./code:/code - ./site.conf:/etc/nginx/conf.d/site.conf links: - php php: image: php:7-fpm volumes: - ./code:/code But how about Apache? How can I set up Apache + PHP in docker-compose.yml? Following this guide: version: '2' services: php: build: php ports: - "80:80" - "443:443" volumes: - ./php/www:/var/www/html Error: ERROR: In file './docker-compose.yml' service 'version' doesn't have any

问题 I'm trying to figure out a problem with identical docker containers being run on different hosts, where one container can find/ping/nslookup a domain on a private network, and another can't. One host is OSX 10.11, the other is Ubuntu 16.04. Both are running docker 1.12. I'm using docker-compose to bring up my application, and I'm hoping to figure out what is going on and how to fix it, or some configuration changes I could make without resorting to hardcoding domains or ip addresses that

问题 Can't get node_modules folder when running yarn install in the Dockerfile test-sof ├── docker-compose.yml ├── Dockerfile ├── package.json └── yarn.lock docker-compose.yml version: '3' services: web: build: . volumes: - .:/myapp package.json { "name": "site", "private": true, "dependencies": { "@rails/webpacker": "^3.2.1", "babel-preset-react": "^6.24.1", "prop-types": "^15.6.0", "react": "^16.2.0", "react-dom": "^16.2.0", "reactjs": "^1.0.0", "underscore": "^1.8.3" }, "devDependencies": {

问题 I have a docker-compose.yml which looks like version: '2' services: redis: image: redis mysqldb: image: mysql:5.7 environment: - MYSQL_ROOT_PASSWORD=passme - MYSQL_DATABASE=mydb - MYSQL_USER=root base: build: . volumes: - .:/proj environment: - ENV_1=Value_1 - ENV_2=Value_2 - ENV_3=Value_3 worker: extends: service: base command: celery -A proj worker --loglevel=debug links: - redis - mysqldb depends_on: - mysqldb web: extends: service: base links: - mysqldb - redis depends_on: - mysqldb ports

问题 I am trying to run mocha unit test for my node application. The application is built by a docker image. Docker image: FROM node:6.10.0-alpine RUN mkdir -p /app WORKDIR /app COPY package.json /app RUN npm install COPY . /app EXPOSE 3000 CMD ["npm", "start"] Docker compose: version: "3" services: web: #### nodejs image build: . volumes: - ./app/ ports: - "3000:3000" depends_on: - db db: build: ##### postgres db image context: . dockerfile: dbDockerfile ports: - 5432:5432 The setup can be built

问题 Setup: I have a virtual machine and in the virtual machine running three containers (an nginx proxy, a very minimalistic flask app and redis). Flask should be serving on port 5000 while redis on 6379. Each of these containers are up and running just fine as stand a lone services, but also available via docker compose as a service . In the flask app, my aim is to connect to redis and query for some keys. The nginx container exposes port 80, flask port 5000 and redis port 6379. In the flask app

问题 I need to know the hostnames (or ip addresses) of some container running on the same machine. As I already commented here (but with no answer yet), I use docker-compose . The documentation says, compose will automatically create a hostname entry for all container defined in the same docker-compose.yml file: Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.

问题 I have 3 images pushed on my private repository in docker hub. Locally, the way I've always run the 3 images is via docker-compose up -d, and it works. Now I'm trying to run this images in a different server so I pushed them in a private repository in docker hub. So in order to run them in the new server this is what I do: 1- I run docker login with my docker hub credentials WARNING! Your password will be stored unencrypted in /home/user/.docker/config.json.
