Rancher service updates

This script written in Go will get all your rancher server services and compare with the latest tag on DockerHub

Getting started

1. Download latest binary release
2. (Optional) Add into your $PATH
3. You need to have some required variables :

• DockerHub username
• DockerHub password
• Rancher API access & secret keys (check http://[SERVER_URL]:[PORT]/env/[ENV]/api/keys)

$ rancher-service-update -u=username -p=password -s=http://[SERVER_URL]:[PORT] --access-key=access_key --secret-key=secret_key # Or via environment

This will print by default a table like :

STACK NAME	SERVICE NAME	IMAGE	ACTUAL TAG	LATEST TAG
Stack 1	api	php	7.2-stretch	7.7-stretch
	front	registry/front	1.1.4	1.1.5
	database	library/postgres	10.3-alpine	10
Other Stack	hello-world	tutum/hello-world	latest	latest
Another Stack	hello-world	...	...	...

If you want to print result as JSON, add the option -o=json. The default is -o=table

Run as Go binary

$ go get github.com/SkYNewZ/rancher-service-update
# Ensure that $GOPATH is set, or if $HOME/go/bin is into your $PATH
$ go-rancher-service-update -u=username -p=password -s=http://[SERVER_URL]:[PORT] --access-key=access_key --secret-key=secret_key # Or via environment variables

Run as docker container

$ docker run -it --rm \
    -e DOCKER_USERNAME=username \
    -e DOCKER_PASSWORD=password \
    -e RANCHER_SERVER_URL=http://[SERVER_URL]:[PORT] \
    -e RANCHER_ACCESS_KEY=access_key \
    -e RANCHER_SECRET_KEY=secret_key \
