The Compose 'networks' key is used as the top-level key in defining the networks to which containers will be connected.
Alachua county official recordsPronounce prophesyDocker uses containers to create virtual environments that isolate a TensorFlow installation from the rest of the system. TensorFlow programs are run within this virtual environment that can share resources with its host machine (access directories, use the GPU, connect to the Internet, etc.). Instead with Docker you simply share two files–a Dockerfile and docker-compose.yml file–and the developer can have confidence that their local development environment is exactly the same as the rest of the team. Docker is not a perfect technology. It is still relatively new, complex under-the-hood, and under active development. Volume mounts will not work on the docker executor because the Docker host running your container is different from the Docker host that you're controlling with docker-compose. Remote volume mounting isn't possible with our setup, but you can get volume mounting with the machine executor.If you make a configuration change to a service and run docker-compose up to update it, the old container is removed and the new one joins the network under a different IP address but the same name. Running containers can look up that name and connect to the new address, but the old address stops working.
The problem is that restart: always policy does not seem to work when I kill the container (simulating app crash using docker kill) and docker-compose does not restart my container, even though the Exit Code is 137. I observe the same behaviour when I use restart: on-failure policy. Versions 2 and 3 of docker-compose behave the same. My system ...
