go-rundeck

Go library and utilities for interacting with Rundeck. It currently supports configuration via environment variables only and supports either token authentication or username/password authentication. (v13 only)

Configuration

• set RUNDECK_URL to the base url of your rundeck installation (i.e. http://localhost:4000 or https://my.rundeck.domain.com)

• set EITHER RUNDECK_TOKEN or RUNDECK_USERNAME and RUNDECK_PASSWORD (only if using v13 api)

• if all three are set RUNDECK_TOKEN takes precendence

Again, username/password authentication are ONLY supported in rundeck.v13 and higher. The original rundeck.v12 only supports token authentication.

Usage

There are two ways to use this:

• as a library
• just for the unmarshal
• via the bundled utilities

as a library

package main

import (
	"fmt"

	rundeck "github.com/lusis/go-rundeck/src/rundeck.v17"
)

func main() {
	/*
		NewClientFromEnv requires two (or three) environement variables:
		- RUNDECK_URL
		- RUNDECK_TOKEN
		if RUNDECK_TOKEN is empty, RUNDECK_USERNAME/RUNDECK_PASSWORD are required
	*/
	client := rundeck.NewClientFromEnv()
	data, err := client.ListProjects()
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Printf("%+v\n", data)
	}
}

for unmarshalling existing data into structs

This is what the test cases do with the mock data

package main

import (
        "encoding/xml"
        "io/ioutil"
        "os"
)

	xmlfile, err := os.Open("assets/test/user_token.xml")
	if err != nil {
		t.Fatal(err.Error())
	}
	defer xmlfile.Close()
	xmlData, _ := ioutil.ReadAll(xmlfile)
	var s Tokens
	xml.Unmarshal(xmlData, &s)

	fmt.Printf("%+v", s)

bundled utilities

cd go-rundeck
make all

Note on versioning

The initial release of this repo was built for rundeck API v12. Each rundeck release adds new or changed functionality. I'm now using a v17 install of Rundeck. The v13 API is the last before several changes in the v14 api.

For now I plan on keeping a different directory for EACH version on the master branch even though there will be quite a bit of code duplication. I reserve the right to make changes to the internals of the library as well in each versioned directory. Some of this is happening with v13 as I ended up shooting myself in the foot with the initial implementation and didn't leave room to change with the rundeck API.

The question becomes how to handle the bundled utilities. I'm likely going to break those out into separate repos and version them separately.

TODO

• Flesh out more tests
• More utilities
• Wrapper cli for sub-utilities
