TL;DR/Notice: If you experience a directory being created in place of the file you are trying to mount, you have probably failed to supply a valid and absolute path. This is a common mistake with a silent and confusing failure mode. File volumes are done this way in docker (absolute path example (can use env … Read more
docker-compose up $ docker-compose up -d –no-deps –build <service_name> –no-deps – Don’t start linked services. –build – Build images before starting containers.
You just need to make sure that the containers you want to talk to each other are on the same network. Networks are a first-class docker construct, and not specific to compose. # front/docker-compose.yml version: ‘2’ services: front: … networks: – some-net networks: some-net: driver: bridge … # api/docker-compose.yml version: ‘2’ services: api: … networks: … Read more
You need to include the following lines in your docker-compose.yml: version: “3” services: app: image: app:1.2.3 stdin_open: true # docker run -i tty: true # docker run -t The first corresponds to -i in docker run and the second to -t.
It is very simple: Use the command: docker-compose restart worker You can set the time to wait for stop before killing the container (in seconds) docker-compose restart -t 30 worker Note that this will restart the container but without rebuilding it. If you want to apply your changes and then restart, take a look at … Read more
Finally found a solution with a docker-compose method. Since docker-compose file format 2.1 you can define healthchecks. I did it in a example project you need to install at least docker 1.12.0+. I also needed to extend the rabbitmq-management Dockerfile, because curl isn’t installed on the official image. Now I test if the management page … Read more
As the handbook describes, you can reuse the Docker daemon from Minikube with eval $(minikube docker-env). So to use an image without uploading it, you can follow these steps: Set the environment variables with eval $(minikube docker-env) Build the image with the Docker daemon of Minikube (eg docker build -t my-image .) Set the image … Read more
Dockerfile A Dockerfile is a simple text file that contains the commands a user could call to assemble an image. Example, Dockerfile FROM ubuntu:latest MAINTAINER john doe RUN apt-get update RUN apt-get install -y python python-pip wget RUN pip install Flask ADD hello.py /home/hello.py WORKDIR /home Docker Compose Docker Compose is a tool for defining … Read more
Unix To delete all containers including its volumes use, docker rm -vf $(docker ps -aq) To delete all the images, docker rmi -f $(docker images -aq) Remember, you should remove all the containers before removing all the images from which those containers were created. Windows – Powershell docker images -a -q | % { docker … Read more
Figured it out, use bash -c. Example: command: bash -c “python manage.py migrate && python manage.py runserver 0.0.0.0:8000” Same example in multilines: command: > bash -c “python manage.py migrate && python manage.py runserver 0.0.0.0:8000″ Or: command: bash -c ” python manage.py migrate && python manage.py runserver 0.0.0.0:8000 “
