I create this application to have a good example around few topic:
- HealthCheck
- HTTP Microservices
- Docker
- 12factor application
And also to have an application to use during my talk/blogpost/article, right now I used that in few occasions:
- http://gianarb.it/blog/docker-1-12-orchestration-built-in
- DockerMeetup in Dublin, resources will be provided soon.
There are two version of this service, they provide both same route, index and health but with few differences:
1.0.0
the healthcheck is really simple, in practice doesn't do any sanity check for Thrid Party service.2.0.0
the healthcheck was written to simulate a dependency with MySQL for this reason it checks if there is alive a MySQL instances. The index has a nice input (nice is too much 😄)
