What is micro-webapps?
The goal of the micro-webapps project is to allow simple deployment of web applications in the cloud (multi container) environment. Admin is able to choose the frontend which will serve the web applications and then install the web applications as separate containers. For each web application, he is able to configure the URI on which the web application will be served.
It is therefore possible to setup webserver with, for example, following structure:
http://domain.tld/running static content.
http://domain.tld/blogrunning wordpress in separate container.
http://bugs.domain.tldrunning Bugzilla in separate container.
http://another-domain.tldrunning completely different domain.
It also allows more advanced features like load-balancing. For more information, check the micro-webapps home page.
What is httpd-frontend-atomicapp?
This Docker image contains Atomic App running HAProxy as frontend for other web applications in the cloud. It is intended to be used with Kubernetes or Openshift. It fetches the list of deployed micro-webapps from the Kubernetes or Openshift API server and sets up the reverse proxy for the web applications.
How to use httpd-frontend-atomicapp?
Using Atomic App is the preferred how to deploy micro-webapps Docker images, but it is also possible to deploy it without the Atomic App as described in the description of microwebapps/httpd-frontend Docker image.
To deploy the httpd-frontend-atomicapp using the Atomic App, all you have to do is running following command:
# atomicapp run microwebapps/httpd-frontend-atomicapp
This downloads all the Docker images needed by the httpd-frontend and deploys it. It will also ask for the configuration variables with their description.
You should now be able to use curl or wget to check that httpd-frontend is responding on the $publicip or on the IP address showed in
kubectl get service or
osc get service output.
Deploying micro-webapps web application
When httpd-frontend is running, you can start deploying micro-webapps web applications. Check the micro-webapps Docker registry for list of supported web applications.
