Stop Container
docker ps
docker stop ${containerName}
docker rm ${containerName}
There is a short hand option to forcefully stop the container:
docker rm -f ${containerName}
Lets try running it again:
docker run -dp 3000:3000 techtonic
docker ps
docker stop ${containerName}
docker rm ${containerName}
docker rm -f ${containerName}
docker run -dp 3000:3000 techtonic
