Receives Webhook calls from Docker Hub and Calls In-Service Upgrades in Rancher
Based on the excellent work of Brian Goff (cpuguy83)
Build a Docker image from the included Dockerfile:
docker build -t myorg/myproject-dockerhub-listener .You must supply these environment variables to start the app listening:
| Environment Variable | Purpose |
|---|---|
api_key |
API Key to use when calling the app (supply as request param in Docker Hub config) |
rancher_url |
The URL if your Rancher Server API root (e.g. http:https://myrancher.example.com:8080/v1/projects/1a2) |
rancher_user_key |
The API Access Key (create via 'API' in the Rancher console) |
rancher_secret_key |
The API Secret Key |
rancher_service |
The name of the rancher service you'd like to upgrade |
Test locally, thus:
docker run -it -p 8080:8080 \
-e api_key="12345" \
-e rancher_url="http:https://myrancher.example.com:8080/v1/projects/1a2" \
-e rancher_user_key="1A2B3C4D5E6F1234567A" \
-e rancher_secret_key="fTEb6aGsD65RhNE32g6yTY1F8hCl5rQTz" \
-e rancher_service="myservice" \
-e listen_addr="0.0.0.0:8080" \
myorg/myproject-dockerhub-listenerAdd a config file using -config-file
This file should be in INI format and is intended for use with handlers
Example
[apiKeys]
key = 1a2b3c4d5e6f
[rancher]
url = http:https://myrancher.example.com:8080/v1/projects/1a2
userkey = <Rancher API User Key>
secretkey = <Rancher API User Secret>
service = <Rancher Service Name>
Register a handler in handler.go
You an use "Logger" as a reference to how to set this up.
cd hub-listener
go build
./hub-listener --listen=0.0.0.0:80 --config-file=config.iniYou should use SSL.
To do so ad a tls section to your config file, with a cert and a key file
You should also use authentication.
Right now DockerHub doesn't really support this, but you can use an api key as a
query param.
To handle this, you need to add an apikeys section to the config file along
with a list of keys
