# Local environment setup

This script configures a full environment to simulate a Gerrit Multi-Site setup.
The environment is composed by:

- 2 gerrit instances deployed by default in /tmp
- 1 zookeeper node
- 1 Broker node (kafka, kinesis or gcloud-pubsub)
- 1 HA-PROXY

## Requirements

- java
- docker and docker-compose
- wget
- envsubst
- haproxy
- aws-cli (only when broker_type is "kinesis")

## Examples

Simplest setup with all default values and cleanup previous deployment. This
will deploy kafka broker

```bash
sh setup_local_env/setup.sh --release-war-file /path/to/gerrit.war --multisite-lib-file /path/to/multi-site.jar
```

Deploy Kinesis broker

```bash
sh setup_local_env/setup.sh \
    --release-war-file /path/to/gerrit.war \
    --multisite-lib-file /path/to/multi-site.jar \
    --broker-type kinesis
```

Deploy GCloud PubSub broker

```bash
sh setup_local_env/setup.sh \
    --release-war-file /path/to/gerrit.war \
    --multisite-lib-file /path/to/multi-site.jar \
    --broker-type gcloud-pubsub
```


Cleanup the previous deployments

```bash
sh setup_local_env/setup.sh --just-cleanup-env true
```

## Limitations

- Assumes the ssh replication is done always on port 22 on both instances
- When cloning projects via ssh, public keys entries are added to `known_hosts`
  - Clean up the old entries when doing a new deployment, otherwise just use HTTP
