hab-two-tier

This Habitat project illustrates a basic Apache web application (webapp) and HAProxy load balancer (haproxy).

The Docker Compose file brings up HAProxy and two load-balanced webapp instances.

Build and Export the packages (inside the studio)

$ hab studio enter
$ build webapp
# Grab the built artifact, i.e. "Artifact: /src/results/learn-chef-webapp-0.2.0-20180105200724-x86_64-linux.hart"
$ hab pkg export docker results/learn-chef-webapp-0.2.0-20180105200724-x86_64-linux.hart
$ build haproxy
# Grab the built artifact, i.e. "Artifact: /src/results/learn-chef-haproxy-1.6.11-20180105200724-x86_64-linux.hart"
$ hab pkg export docker results/learn-chef-haproxy-1.6.11-20180105200724-x86_64-linux.hart
