Build docker image based on the current workdir (denoted by .) by following the instruction in ./Dockerfile give it tag hughluo/docker-example:1.0.0. (pattern for tag: <repo url>/<image name>:<image version>).
docker build -t hughluo/docker-example:1.0.0 .
docker login
docker push hughluo/docker-example:1.0.0
Run a docker container based on image hughluo/docker-example:1.0.0 and publish the containers 8080 port to localhost:9090.
docker run -d -p 9090:8080 hughluo/docker-example:1.0.0
..., and set environment variable LOCATION to Germany.
and pass argument Brendan Eich.
docker run -d -p 9090:8080 --env LOCATION=Germany hughluo/docker-example:1.0.0 Brendan Eich
Modify Dockerfile to let it fail. In this example we modify it to ENTRYPOINT [ "node", "server-not-exist.js" ] so that node will not find the js file to run.
sed "s/server.js/server-not-exist.js/" Dockerfile > BadDockerfile
Build docker image based on the current workdir (denoted by .) and by following the instruction in ./BadDockerfile.
docker build -f BadDockerfile -t hughluo/baddocker-example:1.0.0 .
docker run -d -p 9090:8080 --name badcontainer hughluo/baddocker-example:1.0.0
Check all containers (including dead containers)
docker ps -a
docker image inspect hughluo/baddocker-example:1.0.0
docker inspect badcontainer
