# 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:

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

With this event:

```json
{
"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:

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

With this event:

```json
{
"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:

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

With this event:

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

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

There is no output.
