If you liked the project [docker-git2consul](https://github.com/Cimpress-MCP/docker-git2consul docker-git2consul), you'll love this. We've added suppport for more environment variables. This allows you to spin up git2consul without building a new docker images. Mearly injecting the configuration you'd like to use.

Environment variables:

• CFG - to replace the git2consul config.json
• GIT_REPO - to modify basic config with your git repo(basic config is listed below)
• NAMESPACE - specifys the namespace your objects will come up in
• ID - base64 encoded string of your id_rsa key that is not password protected. (only used if using ssh for repo)
• IDPUB - base64 encoded string of your id_rsa.pub
• CONSUL_ENDPOINT - configures what consul instance to hit
• CONSUL_PORT - configures what consul instance's port to hit

Docker Examples:

docker run \
        --env GIT_REPO=https://username:[email protected]/myuser/myrepo.git \
        --env NAMESPACE=config \
        --env CONSUL_ENDPOINT=192.168.0.111 \
        --env CONSUL_PORT=8500 \
        sroskelley/git2consul

This will download the repo https://github.com/myuser/myrepo.git and feed it into the consul server located at 192.168.0.111:8500

ID=$(cat ~/.ssh/id_rsa|base64)
IDPUB=$(cat ~/.ssh/id_rsa.pub|base64)
CFG='{"version":"1.0","repos":[{"name":"config","url":"[email protected]:myrepo/configs.git","source_root":"dev","mountpoint":"","branches":["master"],"include_branch_name":false,"hooks":[{"type":"polling","interval":"1"}]}]}'
docker run \
        --env CONSUL_ENDPOINT=192.168.0.111 \
        --env CONSUL_PORT=8500
        --env ID="$ID" \
        --env IDPUB="$IDPUB"\
        --env CFG="$CFG" \
        sroskelley/git2consul

This shows how to manually specify your own config and use ssh keys to connect to the git repo.

Basic config embedded in this image:

{
 "version": "1.0",
 "repos" : [{
   "name" : "NAMESPACE",
   "url" : "GIT_REPO",
   "branches" : ["master"],
   "hooks": [{
     "type" : "polling",
     "interval" : "1"
   }]
 }]
}

Its very useless unless you use the NAMESPACE and GIT_REPO envronment variables.

The 6 configs you'd need to set up a consul and its git2consul feeder. lightly borrowed some of michael examples. Thanks Michael!
