docker: invalid reference format on Elixir Umbrella project

following this tutorial I'm trying to dockerize my Elixir Umbrella project before pushing to production.

I'm trying to run my app through Docker using this command:

docker run --rm -ti \
             -p 4000:4000 \
             -e COOKIE=a_cookie \
             -e BASIC_AUTH_USERNAME=UserName \
             -e BASIC_AUTH_PASSWORD=Password \
             -e BASIC_AUTH_REALM=realm \ political_project:0.1.0

I get the following error: docker: invalid reference format. See 'docker run --help'.

As I am new to Docker, I have no clue what the problem might come from.

when I run docker images, I get: 

REPOSITORY                        TAG                 IMAGE ID            CREATED             SIZE

Solution

  • Just remove the last blackslash right in front of the image name 

    docker run --rm -ti \
             -p 4000:4000 \
             -e COOKIE=a_cookie \
             -e BASIC_AUTH_USERNAME=UserName \
             -e BASIC_AUTH_PASSWORD=Password \
             -e BASIC_AUTH_REALM=realm political_project:0.1.0
