go-git-sync will sync JSON or YAML files to Consul when they change in Git.

Basic usage:

$ go-git-sync -c http://consul:8500 sync \
 -s https://github.com/jmoeser/go-git-sync.git \
 -f example/consul/sample-json.json

For example, given a directory test in the repo https://github.com/jmoeser/test-gitops-repo any JSON or YAML files will be synced to the path test/ in Consul.

Contents of the repo

$ tree test/
test/
└── a.json
$ cat test/a.json
{
 "test": "yes",
 "data": "no"
}

Will produce the following in Consul:

$ consul kv get test/a
{
 "test": "yes",
 "data": "no"
}

Changes to these files pushed to Git will update the values as they are in Consul.

Currently the application will poll Git for changes every 3-5 minutes.

Config files are supported you can pass in all the values in the config file instead of passing them in as arguments.

$ go-git-sync --config example/config.yaml sync

Instead of using a config file or command arguments you can use environment variables, just prefix them with GGS_. For example:

$ export GGS_FILE=example/consul/sample-json.json
$ export GGS_SOURCE=https://github.com/jmoeser/go-git-sync.git
$ export GGS_CONSUL="127.0.0.1:8500"
$ go-git-sync sync

To Do:

• Github Webhooks so we don't need to poll
• Store state (last synced Git hash) in Consul instead of SQLite
• Check if hash in Git differs from recorded hash
• Perform sync if hash is different
• Record current Git hash in Consul
• Diff what's in Consul with what we got?
• Option to auto-heal, if the value in Consul changes change it back to what's in Git.
• Vault support (with an intermediate decrypt step)
