⁠S2I Builder for Angular Apps

This repository contains the source for building Angular 2-5 applications based on https://github.com/vilaspatel/s2i-angular-httpd24⁠

For more information about using these images with OpenShift, please see the official OpenShift documentation.

⁠Configuration

The following configuration environment variables are specific to this image:

• NG_ENVIRONMENT - the Angular environment to pass to ng build. This defaults to prod.
• NODE_ENV - this defaults to production.
• NPM_CONFIG_LOGLEVEL - this defaults to info.
• NPM_MIRROR - an NPM registry mirror to use instead of the official NPM registry. Please note that if the mirror uses a certificate signed by an untrusted CA, you'll need to mount the certificate of the untrusted CA in the build container, and use the npm_config_cafile environment variable to point to the mounted CA certificate.

All other environment variables from the base image can also be overriden.

Additionally, you can mount Angular environment files in /tmp/ng-environments/ and they will be copied to ./src/environments/. This is useful if you'd like to override the environment files stored in source.

⁠Installation

To build an Angular Docker image, choose either the CentOS or RHEL based image.

⁠CentOS Based Image

This image is available on DockerHub. To download it, run:

$ sudo docker pull docker pull mprahl/s2i-angular-httpd24

To build your Angular app image with S2I, run:

$ sudo s2i build <git_url> mprahl/s2i-angular-httpd24 <app_image_name>

⁠RHEL Based Image

This image is not on any public registries, so you must build it from scratch. To build it, run:

$ sudo docker build -t mprahl/s2i-angular-httpd24-rhel7 https://raw.githubusercontent.com/mprahl/s2i-angular-httpd24/master/Dockerfile.rhel7

To build your Angular app image with S2I, run:

$ sudo s2i build <git_url> mprahl/s2i-angular-httpd24-rhel7 <app_image_name>

⁠Testing

This repository contains an Angular demo app produced from ng new test-app --minimal in the directory test/test-app. This can be used for testing purposes. To build a Docker image with this demo app, run:

$ sudo s2i build https://github.com/mprahl/s2i-angular-httpd24 \
    --context-dir=test/test-app/ mprahl/s2i-angular-httpd24 angular-demo-app
$ sudo docker run -p 8080:8080 angular-demo-app

You can also run the test script with the following:

$ sudo docker build -t angular-httpd24-candidate .
$ sudo IMAGE_NAME=angular-httpd24-candidate test/run

⁠OpenShift

To use the S2I image within OpenShift, you must create an image stream in your project. To do this, run:

$ oc create -f s2i-angular-httpd24.yml

Alternatively, if you'd prefer to have the OpenShift image stream available globally, you can create the image stream in the openshift namespace. To do this, run:

$ oc create -f s2i-angular-httpd24.yml -n openshift

To view the newly created image stream, run:

$ oc describe imagestream s2i-angular-httpd24

The builder image will now appear as "Angular" under the category "JavaScript" in the OpenShift UI.
