The docker compose (with a space) is a newer project to migrate compose to Go with the rest of the docker project. This is the v2 branch of the docker/compose repo. It’s been first introduced to Docker Desktop users, so docker users on Linux didn’t see the command. In addition to migrating to Go, it … Read more
You can log into the Docker container using the root user (ID = 0) instead of the provided default user when you use the -u option.

Finally, I figured it out! The key point is, just as @SangminKim said, I need to use 3306 not 3302 in settings.py, and use db as HOST not 127.0.0.1. So this is my docker-compose.yml file now: version: ‘3’ services: db: image: mariadb:5.5 restart: always environment: – MYSQL_HOST=localhost – MYSQL_PORT=3306 # cannot change this port to … Read more
Followed this tutorial and it worked. Example Dockerfile: FROM continuumio/miniconda WORKDIR /usr/src/app COPY ./ ./ RUN conda env create -f environment.yml # Make RUN commands use the new environment: SHELL [“conda”, “run”, “-n”, “myenv”, “/bin/bash”, “-c”] EXPOSE 5003 # The code to run when container is started: ENTRYPOINT [“conda”, “run”, “-n”, “myenv”, “python3”, “src/server.py”] Update: … Read more
The latest docker supports setting ulimits through the command line and the API. For instance, docker run takes –ulimit <type>=<soft>:<hard> and there can be as many of these as you like. So, for your nofile, an example would be –ulimit nofile=262144:262144

The main purpose of Docker Compose is to spin up a set of Docker containers, which will then function as independent entities. By default, all containers will have a virtual network connection to all others, though you can change that if you wish; you will get that feature, since you have not specified a custom … Read more
In my case the java application was failing with java.net.UnknownHostException when running in docker. The reason was that I used –network=none docker flag (getting ip/hostname via dhcp and pipework). In this case, docker does not add automatically to /etc/hosts entry like 127.0.0.1 15e326aecf84 And getCanonicalHostName() Java function threw this exception. Possible solutions: add hostname entry … Read more
