Hello World Docker Container
pushed to Docker Hub
Run with:
docker run -d -p 8080:8080 u1ih/hello
Steps:
1: Get Source
git clone https://github.com/u1i/docker-hello
2: Make changes
modify index.html in the app directory
3: Build Container
change into the directory:
cd docker-hello
docker build . -t myhello
4: Run Container
docker run -d -p 8080:8080 myhello
If you experience an error message, you may have another (the previous?) container running on the same port. In this case use this command to kill all running containers:
docker kill $(docker ps -q)
and then try again :-)
5: Optional: Publish to Dockerhub
For this you need to sign up at https://hub.docker.com/ – and get a little familiar with it as well. If you're completely new to this, please ignore this part for now.
docker tag myhello <YOUR_USERNAME>/hello:<VERSION_NUMBER>
docker tag myhello <YOUR_USERNAME>/hello:latest
docker login
docker push <YOUR_USERNAME>/hello:<VERSION_NUMBER>
docker push <YOUR_USERNAME>/hello:latest
