Building go-neb

Go-neb is built using gb (https://getgb.io/). To build go-neb:

# Install gb
go get github.com/constabulary/gb/...

# Clone the go-neb repository
git clone https://github.com/matrix-org/go-neb
cd go-neb

# Build go-neb
gb build github.com/matrix-org/go-neb

Running go-neb

Go-neb uses environment variables to configure its database and bind address. To run go-neb:

BIND_ADDRESS=:4050 DATABASE_TYPE=sqlite3 DATABASE_URL=go-neb.db BASE_URL=https://public.facing.endpoint bin/go-neb

Go-neb needs to connect as a matrix user to receive messages. Go-neb can listen for messages as multiple matrix users. The users are configured using an HTTP API and the config is stored in the database. Go-neb will automatically start syncing matrix messages when the user is configured. To create a user:

curl -X POST localhost:4050/admin/configureClient --data-binary '{
    "UserID": "@goneb:localhost:8448",
    "HomeserverURL": "http://localhost:8008",
    "AccessToken": "<access_token>"
}'
{
    "OldClient": {},
    "NewClient": {
        "UserID": "@goneb:localhost:8448",
        "HomeserverURL": "http://localhost:8008",
        "AccessToken": "<access_token>"
    }
}

Services in go-neb listen for messages in particular rooms using a given matrix user. Services are configured using an HTTP API and the config is stored in the database. Services use one of the matrix users configured on go-neb to receive matrix messages. Each service is configured to listen for messages in a set of rooms. Go-neb will automatically join the service to its rooms when it is configured. To start an echo service:

curl -X POST localhost:4050/admin/configureService --data-binary '{
    "Type": "echo",
    "Id": "myserviceid",
    "Config": {
        "UserID": "@goneb:localhost:8448",
        "Rooms": ["!QkdpvTwGlrptdeViJx:localhost:8448"]
    }
}'
{
    "Type": "echo",
    "Id": "myserviceid",
    "OldConfig": {},
    "NewConfig": {
        "UserID": "@goneb:localhost:8448",
        "Rooms": ["!QkdpvTwGlrptdeViJx:localhost:8448"]
    }
}

Go-neb has a heartbeat listener that returns 200 OK so that load balancers can check that the server is still running.

curl -X GET localhost:4050/test

{}

Starting a Github Service

Register a Github realm

curl -X POST localhost:4050/admin/configureAuthRealm --data-binary '{
    "ID": "mygithubrealm",
    "Type": "github",
    "Config": {
        "ClientSecret": "YOUR_CLIENT_SECRET",
        "ClientID": "YOUR_CLIENT_ID",
        "RedirectBaseURI": "https://public.path.to.neb"
    }
}'

Returns:

{
  "ID":"mygithubrealm",
  "Type":"github",
  "OldConfig":null,
  "NewConfig":{
    "ClientSecret":"YOUR_CLIENT_SECRET",
    "ClientID":"YOUR_CLIENT_ID",
    "RedirectBaseURI":"https://public.path.to.neb"
  }
}

Make a request for Github Auth

curl -X POST localhost:4050/admin/requestAuthSession --data-binary '{
    "RealmID": "mygithubrealm",
    "UserID": "@your_user_id:localhost",
    "Config": {
    }
}'

Returns:

{
  "URL":"https://github.com/login/oauth/authorize?client_id=$ID\u0026client_secret=$SECRET\u0026redirect_uri=$REDIRECT_BASE_URI%2Frealms%2Fredirects%2Fmygithubrealm\u0026state=$RANDOM_STRING"
}

Create a github bot

curl -X POST localhost:4050/admin/configureService --data-binary '{
    "Type": "github",
    "Id": "mygithubserviceid",
    "Config": {
    	"RealmID": "mygithubrealm",
        "BotUserID": "@goneb:localhost",
        "ClientUserID": "@example:localhost",
        "Rooms": {
        	"!EmwxeXCVubhskuWvaw:localhost": {
        		"Repos": {
        			"owner/repo": {
        				"Events": ["push","issues"]
        			}
        		}
        	}
        }
    }
}'

This request will make BotUserID join the Rooms specified and create webhooks for the owner/repo projects given.

Starting a JIRA Service

Register a JIRA realm

Generate an RSA private key: (JIRA does not support key sizes >2048 bits)

openssl genrsa -out privkey.pem 2048
cat privkey.pem

Create the realm:

curl -X POST localhost:4050/admin/configureAuthRealm --data-binary '{
    "ID": "jirarealm",
    "Type": "jira",
    "Config": {
        "JIRAEndpoint": "matrix.org/jira/",
        "ConsumerName": "goneb",
        "ConsumerKey": "goneb",
        "ConsumerSecret": "random_long_string",
        "PrivateKeyPEM": "-----BEGIN RSA PRIVATE KEY-----\r\nMIIEowIBAAKCAQEA39UhbOvQHEkBP9fGnhU+eSObTWBDGWygVYzbcONOlqEOTJUN\r\n8gmnellWqJO45S4jB1vLLnuXiHqEWnmaShIvbUem3QnDDqghu0gfqXHMlQr5R8ZP\r\norTt1F2idWy1wk5rVXeLKSG7uriYhDVOVS69WuefoW5v55b5YZV283v2jROjxHuj\r\ngAsJA7k6tvpYiSXApUl6YHmECfBoiwG9bwItkHwhZ\/fG9i4H8\/aOyr3WlaWbVeKX\r\n+m38lmYZvzQFRAk5ab1vzCGz4cyc\r\nTk2qmZpcjHRd1ijcOkgC23KF8lHWF5Zx0tySR+DWL1JeGm8NJxKMRJZuE8MIkJYF\r\nryE7kjspNItk6npkA3\/A4PWwElhddI4JpiuK+29mMNipRcYYy9e0vH\/igejv7ayd\r\nPLCRMQKBgBDSNWlZT0nNd2DXVqTW9p+MG72VKhDgmEwFB1acOw0lpu1XE8R1wmwG\r\nZRl\/xzri3LOW2Gpc77xu6fs3NIkzQw3v1ifYhX3OrVsCIRBbDjPQI3yYjkhGx24s\r\nVhhZ5S\/TkGk3Kw59bDC6KGqAuQAwX9req2l1NiuNaPU9rE7tf6Bk\r\n-----END RSA PRIVATE KEY-----"

Returns:

    }
}

The ConsumerKey, ConsumerSecret, ConsumerName and PublicKeyPEM must be manually inserted into the "Application Links" section under JIRA Admin Settings by a JIRA admin on the target JIRA installation. Once that is complete, users can OAuth on the target JIRA installation.

Make a request for JIRA Auth

curl -X POST localhost:4050/admin/requestAuthSession --data-binary '{
    "RealmID": "jirarealm",
    "UserID": "@example:localhost",
    "Config": {
    }
}'

Returns:

    "URL":"https://jira.somewhere.com/plugins/servlet/oauth/authorize?oauth_token=7yeuierbgweguiegrTbOT"
}

                }
            }
        }
    }
}'

Developing on go-neb.

There's a bunch more tools this project uses when developing in order to do things like linting. Some of them are bundled with go (fmt and vet) but some are not. You should install the ones which are not:

go get github.com/golang/lint/golint
go get github.com/fzipp/gocyclo

You can then install the pre-commit hook:

./hooks/install.sh
