You can use a Dockerfile to build new container images. Dockerfile provides a simple syntax for building Linux or Windows containers. You can learn more about the Dockerfile here (https://docs.docker.com/engine/reference/builder/) Let's build a container for funfact application.
git pull [email protected]:faheem556/funfact.git
cd funfact
# build dotnet app
docker build -t funfact:dotnet-1-0 -f dotnet/Dockerfile ./funfact/dotnet
# build node image
docker build -t funfact:node-1-0 -f nodejs/Dockerfile ./funfact/nodejs
# build java image
docker build -t funfact:java-1-0 -f java/Dockerfile ./funfact/java
Read through the code and docker files to understand the environement. It's really straight-forward.
Let's run the application now.
docker run --name funfactd -d --rm -p 8080:80 funfact:dotnet-1-0
docker run --name funfactn -d --rm -p 8081:80 funfact:node-1-0
docker run --name funfactj -d --rm -p 8082:80 funfact:java-1-0
docker ps
You should have three running containers at this point. If for some reason the container doesn't start, you can use docker ps -a and docker log to troubleshoot.
Once the containers are up, open you browsers and try out the applications.
Cleanup
docker stop funfactd
docker rm funfactd
docker stop funfactn
docker rm funfactd
docker stop funfactj
docker rm funfactj
