deployer-tools

A utility that evaluates a mapping of project branches to services in clusters, outputting docker swarm actions.

Usage

Usage: deployer-tools [options]
  Helps deploy things.
Options:
  -dry
    	Prefixes all output with '#' characters.
  -event string
    	The location of the event file.
  -host-template string
    	The template used to build the host DNS entry.
  -mapping string
    	The location of the mapping file.
  -test
    	Use to test scripts.

Ideal usage is to pipe the output into bash.

$ ./deployer-tools -event event.json -mapping mapping.json | sh

Using the -dry flag will prefix all output with '# '.

$ ./deployer-tools -event event.json -mapping mapping.json -dry
# docker -H manager01.greeting.internal:2375 service update --image ngerakines/hello-world-nodejs:CI1 hello
# docker -H manager01.greeting.internal:2375 service update --image ngerakines/hello-world-nodejs:CI1 goodbye

Using -test will output several echo lines used for script testing.

$ ./deployer-tools -test
echo 'deployer-tools test'

Example 1

With the following mapping:

{
   "hello-world": {
      "master": {
         "greeting": ["hello"]
      }
   },
   "project": {
      "branch": {
         "cluster": ["service"]
      }
   }
}

With this event:

{
  "Project":"hello-world",
  "Branch":"master",
  "Container":"ngerakines/hello-world-nodejs:CI1"
}

$ ./deployer-tools -mapping mapping.json -event event.json
docker -H manager01.greeting.internal:2375 service update --image ngerakines/hello-world-nodejs:CI1 hello

Example 2

With the following mapping:

{
   "hello-world": {
      "master": {
         "greeting": ["hello", "goodbye"]
      }
   },
   "project": {
      "branch": {
         "cluster": ["service"]
      }
   }
}

With this event:

{
  "Project":"hello-world",
  "Branch":"master",
  "Container":"ngerakines/hello-world-nodejs:CI1"
}

$ ./deployer-tools -mapping mapping.json -event event.json
docker -H manager01.greeting.internal:2375 service update --image ngerakines/hello-world-nodejs:CI1 hello
docker -H manager01.greeting.internal:2375 service update --image ngerakines/hello-world-nodejs:CI1 goodbye

Example 3

With the following mapping:

{
   "hello-world": {
      "master": {
         "greeting": ["hello", "goodbye"]
      }
   },
   "project": {
      "branch": {
         "cluster": ["service"]
      }
   }
}

With this event:

{
  "Project":"hello-world",
  "Branch":"feature-1234",
  "Container":"ngerakines/hello-world-nodejs:CI1"
}

$ ./deployer-tools -mapping mapping.json -event event.json

There is no output.
