I propose that we create one uber-example to be hosted in the Nulecule Specification and move all the rest to a library, like CentOS-Dockerfile, Fedora-Dockerfiles
User Story As a cool blogger, I want to host a WordPress that scales, so that I can receive many many hits.
A frontend nginx ephemeral reverse proxy will provide scale out capabilities: as more hits the blog receives, we increase the number ob nginx proxies. These proxies are place in front of a WordPress blog, CSS is contained in myWordPress image. There will be one WordPress 'application server'. Data is stored in a cluster of MySQL Master/Slaves. The database layer will use replication to increase data availability.
@goern I don't disagree but do we want this particular example to live on (maybe in another location)? If so then we would need to fix this issue.
I don't think these example Dockerfiles should land in CentOS-Dockerfiles and/or Fedora-Dockerfiles. Because these are not typical Dockerfiles but specific to Nulecule and Atomic App.
If we really want a new home, then we should create a separate github repo under projectatomic and some interested folks can maintain this.
The good think about having separate repo is that we can open it (i.e. have separate directory structures) for Dockerfiles based on different Linux/GNU distributions.
Both these approaches makes sense - Fedora/CentOS-Docekrfiles lets us to introduce these examples to wider audience as they are already know and used.
New repostory would make it easier for people to find Nulecules specifically...
I am more inclined to moving the examples to *-Dockerfiles repositories.
I like the idea of an uber example, in the Nulecule repo. We should get one more and a helloapache example we are all happy with.
For me this fails as well but with:

Why does it complain about Nulecule not being found?
Btw. I am using ADB.
Here is another approach to solve this issue, https://trello.com/c/nBiEJxic
Not sure what is wrong with this example but the wordpress container in the kubernetes pod just keeps restarting and the logs from one of them is:
One issue I see is that we are pulling from
goern/wordpress
for this. Might be a good thing to create something official and pull from that.
