docker postgres failed to start with specified port

Question

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

Answer 1

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.
