+# Building kube-cert-manager using AWS CodeBuild
+
+You can use AWS CodeBuild to build this project and push the contianer image to Docker hub.
+You can use the AWS console or the AWS CLI with the scripts in the `codebuild` folder.
+
+## Console Set-up
+
+Use the AWS CodeBuild console to create a CodeBuild project as follows
+
+- Give the project a name
+- Select the GitHub project to build
+- Choose build image: 'aws/codebuild/docker:1.12.1'
+- Opt to use the 'buildspec.yml' file
+- Choose 'No Artifacts'
+- Choose (or create) the AWS Service Account to use
+
+## Console Build
+
+Use the AWS CodeBuild console to start the build
+
+1. Choose 'Start Build'
+2. If necessary, enter the git branch or commit ID
+3. Add or update the following environment variables
+```
+CONTAINER_VERSION
+DOCKER_REPO
+DOCKER_HUB_USERNAME
+DOCKER_HUB_PASSWORD
+```
+4. Start the Build
+5. Check the build logs afterwards
+
+## CLI Set-up
+
+This requires you have [AWS CLI installed](http://docs.aws.amazon.com/cli/latest/userguide/installing.html), 
+a CodeBuild Service Account, and have linked CodeBuild to GitHub.
+
+1. Update the GitHub URL and AWS Service Account in the `cloudbuild.json` file
+2. Create the project, specifying your profile and the region if not your default
+```
+aws codebuild create-project --profile default --region=us-east-1 --cli-input-json file://codebuild-project.json
+```
+
+## CLI Build
+
+1. Set the following environment variables or customise `build.env` and `source build.env`
+```
+export PROJECT_NAME="kube-cert-manager"
+export PROJECT_REGION="us-east-1"
+export SOURCE_VERSION=""
+export CONTAINER_VERSION="0.4.0"
+export DOCKER_REPO=<your Docker Hub repo name>
+export DOCKER_HUB_USERNAME=<your username>
+export DOCKER_HUB_PASSWORD=<your password>
+```
+2. Start the build with `start-codebuild.sh`
+3. View the build log with `get-codebuild-log.sh`
