I'm new to docker and I'm trying to run a postgres database docker with the following command :
docker run --name rva-db -e POSTGRES_PASSWORD=rva -e POSTGRES_DB=rva-db -d postgres -p 5432:5432
If I'm trying to run it without the -p option, it seems to work fine, but I can't reach it from my local pg-admin, I thought I need to add the port link to reach it.
Anyway, the container always crash after few seconds and when i'm trying to start it with the start command I'm getting the following return :
docker start -a rva-db
FATAL: invalid value for parameter "port": "5432:5432"
What did I miss ?
FYI, I'm running it on a MacOS with the following docker version :
$ docker version

Run the container typing -p option before the image name
docker run --name rva-db -e POSTGRES_PASSWORD=rva -e POSTGRES_DB=rva-db -d -p 5432:5432 postgres
As for Docker run reference docker run has this format
docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]
Options must be before image name. After that you can set entrypoint or command (when theyy differ from default from Dockerfile) and their arguments.
