Separate replica from master Not having a specific placement strategy for replica might cause it to be deployed on the same ec2-instance as the master. If tasks are running on the same instance, both source and destination IP are the same when being received by the target instance and this causes packets to be dropped as per convention for L4 networking[1]. Ensure replica is never deployed to the same ec2-instance as the master by creating separate ASG for master and replica. Since the cluster is now composed by different autoscaling groups, rather than one, the DESIRED_CAPACITY variable cannot be used to specify the size of the cluster as a whole, as each autoscaling group has its own size. The master ASG is defined as such: * minimum:1 - desired:1 - maximum: configurable via the MASTER_MAX_COUNT The slave ASG does not yet have the ability to scale (it's in the roadmap to do[2]): * minimum:1 - desired:1 - maximum:1 [1]https://aws.amazon.com/premiumsupport/knowledge-center/target-connection-fails-load-balancer/ [2]https://bugs.chromium.org/p/gerrit/issues/detail?id=13619 Bug: Issue 13879 Change-Id: I306610e9b5720363f730765d9f9332d0b7f52814
Those are a collection of AWS CloudFormation templates and scripts to deploy Gerrit in AWS.
The aim is to provide some guidelines and example on how to deploy different Gerrit setups in the Cloud using AWS as provider.
The goal of Gerrit AWS Templates is to provide fully-functional Gerrit installations to helps users deploying Gerrit on AWS by providing out-of-the-box templates.
With Gerrit AWS Templates, developers and administrator can create a production-ready installation on the cloud in minutes and in a repeatable way, allowing them to focus on fine tuning of the Gerrit configuration to suit the user needs.
The provided CloudFormation templates automate the entire creation and deployment of the infrastructure and the application.
To manage your AWS services via command line you will need to install AWS CLI and set it up to point to your account.
To build gerrit and related-components' images Docker
To manipulate aws cloudformation outputs jq
This is a list of external services that you might need to setup your stack and some suggestions on how to easily create them.
If you need to setup a SMTP service Amazon Simple Email Service can be used. Details how setup Amazon SES can be found here.
To correctly setup email notifications Gerrit requires ssl protocol on default port 465 to be enabled on SMTP Server. It is possible to setup Gerrit to talk to standard SMTP port 25 but by default all EC2 instances are blocking it. To enable port 25 please follow this link.
If you need a testing LDAP server you can find details on how to easily create one in the LDAP folder.
