After trying it and solving a myriad of problems along the way, I have realized that it is simply the documentation that is out of date. Adding the following yaml block to my docker-compose.yml resulted in nvidia-smi being available to use. deploy: resources: reservations: devices: – driver: nvidia count: 1 capabilities: [gpu]
To elaborate on the original accepted answer, just change your docker-compose.yml file so that it contains this as your entrypoint: version: “3.7” services: server: image: alpine:latest secrets: – test entrypoint: [ ‘/bin/sh’, ‘-c’, ‘export TEST=$$(cat /var/run/secrets/test) ; source /entrypoint.sh’ ] secrets: test: external: true That way you don’t need any additional files!
I was wondering the same thing and found this: https://github.com/docker/compose/issues/4513 So in short it’s just not possible to do that, you have to use the version 2.1 of the docker-compose format to be able to specify limits that are not ignored by docker-compose up
You may have to switch to version: 3 to do this, I believe on version: 2 you can use the “scale” parameter but I’m not 100% sure. Anyways, you can override the “replicas” parameter like this: # docker-compose.prod.yml version: “3” services: db_for_development: deploy: replicas: 0
I have been doing some testing in this regards, it looks like the /var/run directory is special in docker. Here is some sample config and output: ubuntu: image: ubuntu command: “bash -c ‘mount'” tmpfs: – /var/run – /var/cache Running docker-compose up ubuntu shows what is mounted. Can see /var/cache is mounted but /var/run isn’t. … … Read more
~/.docker/config.json should work for this version: “3” services: watchtower: image: v2tec/watchtower volumes: – /var/run/docker.sock:/var/run/docker.sock – ~/.docker/config.json:/config.json
UPDATE: 20230829 Fixed Automating download of latest release of docker-compose Last update of curl apparently didn’t like my script to automate the download of the latest release of docker-compose. So here’s the re-jiggered script which is tested and known to work with Ubuntu 22.04.3. Since GitHub doesn’t like IPv6, I forced IPv4 in the curl … Read more
You can specify multiple env files on the env_file option (without s). For instance: version: ‘3’ services: hello: image: alpine entrypoint: [“sh”] command: [“-c”, “env”] env_file: – a.env – b.env
Docker is the command-line tool that uses containerization to manage multiple images and containers and volumes and such — a container is basically a lightweight virtual machine. See https://docs.docker.com/ for extensive documentation. Until recently Docker didn’t run on native Mac or Windows OS, so another tool was created, Docker-Machine, which creates a virtual machine (using … Read more
I’ve had a fair amount of experience with microservices and local development and here’s been some approaches I’ve seen: Run all the things locally on docker or k8. If using k8, then a tool like skaffolding can make it easier to run and debug a service locally in the IDE but put it into your … Read more
