According to the docker-compose and docker run reference, the user option sets the user id (and group id) of the process running in the container. If you set this to 1000:1000, your webserver is not able to bind to port 80 any more. Binding to a port below 1024 requires root permissions. This means you … Read more
Since many Docker Compose users have complained about this incompatibility of compose v3 vs v2, the team has developed compatibility mode. You can retain the same deploy structure that you provided and it will not be ignored, simply by adding the –compatibility flag to the docker-compose command (docker-compose –compatibility up), as explained here. I tested … Read more
As stated on the edit on my question the problem was that CMD from nginx:1.11 was only starting the nginx process. A work around is to place the following command on my Dockerfile CMD service cron start && nginx -g ‘daemon off;’ This will start nginx as nginx:1.11 starts it and well as start the … Read more
Docker is telling you that the command hit an error. It is trying to run the node image with the command -w. Since -w is not a command, it throws this error. This is because you have written node in a place you probably didn’t mean to. Your command is being interpreted like this: docker … Read more
You can stop the build at a certain stage and tag them as you want. docker build –target test -t starx/test:latest . docker build –target staging -t starx/staging:latest . docker build –target prod -t starx/prod:latest . This way, you have different images and you can push each image individually.
The other answer indeed points to the root cause of the problem, however the help page it points to does not contain a solution. Here is what I came up with to make this work for me: start the container using your normal docker-compose file, this creates the directory with the hardcoded uid:gid (999:999) version: … Read more
Installing the Chrome .deb file this way won’t work on Alpine. While the dpkg package is available in the Alpine repository, and is useful for installing lightweight Debian packages, you won’t be able to use it for installing complex Debian packages, since it’ll be impossible to satisfy many Debian dependencies. Alpine is generally not Debian … Read more
You don’t have to set the IP, but you can reference the container’s virtual hostname, and this is the same value as you named your linked container. This means you can indeed set the DB_HOST from within the docker-compose.yml, either with links (recommended) or external_links: your_application: build: . ports: – “9180:80” – “9543:443” external_links: – … Read more
After searching and trying many different scenarios, I was able to add waiting using the following composer file. This is for asp.net core solution. The key is that you have to overwrite entrypoint if it is specified in dockerfile. Also, you need to make sure to save “wait-for-it.sh” LF as line ending instead of CRLF, … Read more
The standard mechanism is not to ssh into containers, but to connect to a container using docker exec. Given a container Id like 3cdb7385c127 you can connect (aka ssh into it) with docker exec -it 3cdb7385c127 sh or for a full login shell if you have bash available in container docker exec -it 3cdb7385c127 bash … Read more
