[go-discover](https://github.com/hashicorp/go-discover) library for doing
automatic cluster joining using cloud metadata. To use retry-join with a
supported cloud provider, specify the configuration on the command line or
configuration file as a `key=value key=value ...` string. The values need to
be URL encoded but for most practical purposes you need to replace spaces
with `+` signs.
configuration file as a `key=value key=value ...` string.
In Consul 0.9.1-0.9.3 the values need to be URL encoded but for most
practical purposes you need to replace spaces with `+` signs.
As of Consul 1.0 the values are taken literally and must not be URL
encoded. If the values contain spaces, backslashes or double quotes then
they need to be double quoted and the usual escaping rules apply.
```sh
$ consul agent -retry-join "provider=my-cloud config=val ..."
$ consul agent -retry-join 'provider=my-cloud config=val config2="some other val" ...'
```
or via a configuration file:
```json
{
"retry_join": ["provider=my-cloud config=val ..."]
"retry_join": ["provider=my-cloud config=val config2=\"some other val\" ..."]
}
```
