I am president to the Elixir forum and helping people out. I have been using Elixir for 5 years; in the past I have used C++ and others. 1:46 – Chuck: App env and configuration and sounds like we could talk about more. Let’s start there, though. 1:59 – Guest. 2:03 – Panel: A little background with configuration b/c it’s been a topic in the community. There is a lot of discussion around it. What is the right way? And there is a change in how we deploy software. We have more docker containers and multiple stages of deployment and tons of configurations through environment settings. Anything you can talk about that? 2:51 – (Guest answers those questions. He discusses in detail about https://docs.docker.com/engine/reference/commandline/config/ Also, the guest talks about the various settings per the different environments.) 7:25 – Panel: That was a thorough summary. 7:29 – Guest: I can talk more. 7:35 – Panel: So we have background on configuration is setup and the goals we have.

There is usually more than 1 configuration file. 17:53 – Panel: You only get agreement. I have had that problem, too, saying what is this configuration? What are THE Settings that are present and yeah that is a problem? You identify these problems in your blog, where it’s not checked in and the code will not...
