Goal
We will create a Docker image running on Public IP which gets deployed on Oracle Container Cloud Services, the docker sources will be available in Github and Build process will be managed by Docker Hub
To do this you would need the following
- Oracle Container Cloud Service Instance running
- GitHub account ( https://github.com/ )
- Docker Hub account ( https://hub.docker.com/ )
Connect Docker Hub with Git Repo
Login to https://hub.docker.com/ , Select the dropdown of your profile name at extreme right, click on Settings, click on Linked Accounts and Services, Link with Github
Link with Github, this might ask for github login if you are already not logged into github
Fork Repo into your Github
Login to your GitHub account at https://github.com/login , ii. Go to application repository at docker-hello-world Click on Fork button at the top of the repository page
Automated Builds
Access Docker Hub, Select Create Automated Builds, click on Create Auto-builds from Github
this should show docker-images , click on that
select Repository name , name for the build and also description , select public option and then create button
You can now view the Repository info
click on build settings, for the Master give Docker file as “/ContainerCloud/images/docker-hello-world/” , Docker tag name as latest
Save changes.
You can now Trigger a build
the Repository Info will now be updated , please copy the docker file name in this case it is jamessmith73/docker-images_madhus_world
View Docker file info
Login to Oracle Container Cloud Service
Select Services , from the left navigation and click on New Service Button
Image name should match the one with docker hub image that we created, jamessmith73/docker-images_madhus_world
Check the Ports option, select Host Port as 8080 and Container Port as 80
Click on Save,
Deploy the Service
Select Resource Pool as Production or Default , now we should be able to see Public IP , the docker should be accessable at http://public ip:8080
Changing the Docker content at Github
Edit the index.html file in our repo save changes by commiting
Trigger the build , now the new version of content should be visible at public ip address
