This Quick Start was created by Atlassian in collaboration with Amazon Web Services (AWS). Quick Starts are automated reference deployments that use AWS CloudFormation templates to deploy key technologies on AWS, following AWS best practices.

Overview

This Quick Start is for users who want to deploy Bitbucket Data Center in a supported configuration in the AWS Cloud, following AWS and Atlassian best practices.

This Quick Start uses the Atlassian Standard Infrastructure (ASI) as a foundation. You can choose to build a new ASI for your deployment or deploy Bitbucket into your existing ASI. You can also deploy Jira, Confluence, and Crowd Data Center within the same ASI.

Amazon may share user-deployment information with the AWS Partner that collaborated with AWS on the Quick Start.

Bitbucket Data Center on AWS

Bitbucket Data Center is a Git repository management solution from Atlassian. It provides source code collaboration for enterprises that require high availability and performance at scale.

Please know that we may share who uses AWS Quick Starts with the AWS partner that collaborated with AWS on the content of the Quick Start.

AWS costs

You are responsible for the cost of the AWS services and any third-party licenses used while running this Quick Start. There is no additional cost for using the Quick Start.

The AWS CloudFormation templates for Quick Starts include configuration parameters that you can customize. Some of the settings, such as the instance type, affect the cost of deployment. For cost estimates, see the pricing pages for each AWS service you use. Prices are subject to change.

After you deploy the Quick Start, create AWS Cost and Usage Reports to deliver billing metrics to an Amazon Simple Storage Service (Amazon S3) bucket in your account. These reports provide cost estimates based on usage throughout each month and aggregate the data at the end of the month. For more information, see What are AWS Cost and Usage Reports?

Software licenses

This Quick Start deploys a cluster-ready infrastructure for Bitbucket. This requires a Bitbucket Data Center license. See the Atlassian pricing page for licensing information.

Architecture

Deploying this Quick Start for a new Atlassian Standard Infrastructure (ASI) with default parameters builds the following Bitbucket environment in the AWS Cloud.

Figure 1. Quick Start architecture for Bitbucket on AWS

As shown in Figure 1, the Quick Start sets up the following:

A highly available architecture that spans two Availability Zones.
In the public subnets:
- A network address translation (NAT) gateway to allow outbound internet access for resources in the private subnets.
- A bastion host that enables secure access to Bitbucket without exposing it to the internet. For more information, see Bastion Hosts). You can choose not to provision a bastion host if you prefer to access Bitbucket nodes through the AWS Systems Manager.
In the private subnets:
- A network file system (NFS) server instance. This provides a shared file system with an attached Amazon Elastic Block Store (Amazon EBS) volume for storing repositories.
- Amazon Relational Database Service (Amazon RDS) for PostgreSQL in a high-availability (Multi-AZ) configuration, which mitigates failover if the master node fails. You can choose Amazon Aurora PostgreSQL instead.
Amazon Elastic Compute Cloud (Amazon EC2) Auto Scaling groups for scaling the bastion hosts in the public subnets and the Bitbucket nodes in the private subnets. The instances are based on Amazon Linux, a Linux server operating system from AWS, and use an Atlassian-provided Amazon Machine Image (AMI).
An Amazon Elastic Load Balancer, which works both as a load balancer and a Secure Sockets Layer (SSL) termination reverse proxy.
Amazon Elasticsearch Service (Amazon ES) for Elasticsearch 2.3 indexing and searching functionality.
Amazon CloudWatch for basic monitoring of all application and database nodes in your deployment. By default, CloudWatch collects and stores logs from each monitored node. Amazon CloudWatch is an optional component.

Amazon Elasticsearch

Bitbucket Data Center uses Elasticsearch 2.3 for indexing and searching. The Quick Start architecture uses the Amazon Elasticsearch Service (Amazon ES), which is a managed service that makes it easy to deploy, operate, and scale Elasticsearch in the AWS Cloud.

NFS for shared storage

Bitbucket Data Center uses a shared network file system (NFS) to store the repositories in a common location that is accessible to multiple Bitbucket nodes. The Quick Start architecture implements the shared file system in an Amazon Elastic Compute Cloud (Amazon EC2) instance with an attached Amazon Elastic Block Store (Amazon EBS) volume. We recommend that you create regular snapshots of the EBS volume at a frequency that meets the recovery point objective (RPO) of your organization. If using a single EBS volume doesn’t meet your availability and disaster recovery requirements, you should consider a highly available NFS implementation using AWS partner products.

Auto Scaling groups in this Quick Start

This Quick Start uses Auto Scaling groups to statically control the number of its nodes. Don’t use Auto Scaling to dynamically scale the size of your cluster. Adding an application node to the cluster usually takes more than 20 minutes, which isn’t fast enough to address sudden load spikes.

If you can identify periods of high and low loads, you can schedule the application node cluster to scale accordingly. For more information, see Scheduled Scaling for Amazon EC2 Auto Scaling.

To study trends in your organization’s load, be sure to monitor the performance of your deployment.

Amazon Aurora database for high availability

The Quick Start also allows you to deploy Bitbucket Data Center with an Amazon Aurora clustered database (instead of RDS).

You can also use this Quick Start to deploy Bitbucket Data Center with an Aurora clustered database that’s compatible with PostgreSQL. The cluster configuration is illustrated in Figure 2. It features a primary database writer that replicates to two database readers in a different Availability Zone. If the writer fails, Aurora promotes one of the readers to take its place with no downtime. For more information, see Amazon Aurora Features: PostgreSQLCompatible Edition.

The Aurora configuration with a single database writer and two readers is designed to provide high availability without degrading performance.

Figure 2. Amazon Aurora reader/writer configuration

Amazon Aurora is supported on Bitbucket Data Center 6.7 and later.

Planning the deployment

Specialized knowledge

This deployment requires a moderate level of familiarity with AWS services. If you’re new to AWS, see Getting Started Resource Center and AWS Training and Certification. These sites provide materials for learning how to design, deploy, and operate your infrastructure and applications on the AWS Cloud.

This Quick Start assumes familiarity with managing Atlassian Bitbucket. Refer to the latest Atlassian documentation on Bitbucket for more information.

AWS account

If you don’t already have an AWS account, create one at https://aws.amazon.com by following the on-screen instructions. Part of the sign-up process involves receiving a phone call and entering a PIN using the phone keypad.

Your AWS account is automatically signed up for all AWS services. You are charged only for the services you use.

Technical requirements

Before you launch the Quick Start, review the following information and ensure that your account is properly configured. Otherwise, deployment might fail.

Resource quotas

If necessary, request service quota increases for the following resources. You might need to request increases if your existing deployment currently uses these resources and if this Quick Start deployment could result in exceeding the default quotas. The Service Quotas console displays your usage and quotas for some aspects of some services. For more information, see What is Service Quotas? and AWS service quotas.

variable based on user configuration

Supported AWS Regions

For any Quick Start to work in a Region other than its default Region, all the services it deploys must be supported in that Region. You can launch a Quick Start in any Region and see if it works. If you get an error such as “Unrecognized resource type,” the Quick Start is not supported in that Region.

For an up-to-date list of AWS Regions and the AWS services they support, see AWS Regional Services.

Certain Regions are available on an opt-in basis. For more information, see Managing AWS Regions.

IAM permissions

Before launching the Quick Start, you must sign in to the AWS Management Console with IAM permissions for the resources that the templates deploy. The AdministratorAccess managed policy within IAM provides sufficient permissions, although your organization may choose to use a custom policy with more restrictions. For more information, see AWS managed policies for job functions.

Deployment options

This Quick Start includes two AWS CloudFormation templates. The first template builds the Atlassian Standard Infrastructure (ASI), which is a virtual private cloud (VPC) that contains the components required by all Atlassian applications, and then provisions Bitbucket into this ASI. The second template provisions Bitbucket in an existing ASI.

Using these templates, the Quick Start provides two deployment options:

Deploy Bitbucket Data Center into a new ASI (end-to-end deployment). Choose this option if you’re a new user. This option builds the Atlassian Standard Infrastructure (ASI), which is a VPC that consists of the subnets, NAT gateways, security groups, and other infrastructure components required by all Atlassian applications. It then deploys Bitbucket into this new VPC.
Deploy Bitbucket Data Center into an existing ASI. This option provisions Bitbucket in an existing ASI, and also offers more customizable parameters. Choose this option if you’ve already deployed the ASI separately by using the ASI Quick Start, or by deploying another Atlassian product from a Quick Start (Jira Software/Service Desk Data Center, Confluence Data Center, Bitbucket Data Center, or Crowd Data Center).

The Quick Start provides separate templates for these options. It also lets you configure Classless Inter-Domain Routing (CIDR) blocks, instance types, and Bitbucket settings, as discussed later in this guide.

Deployment steps

Launching from a cloned Quick Start (recommended for production)

The fastest way to deploy Bitbucket with this Quick Start is directly through its AWS Quick Start interface. However, when you deploy Bitbucket this way, any updates that are made to the Quick Start templates propagate directly to your production deployment. These updates sometimes involve adding or removing parameters, which could introduce unexpected changes or break your deployment.

As a best practice, instead of deploying directly through the AWS Quick Start interface, clone the Bitbucket Quick Start templates to a custom Amazon Simple Storage Service (Amazon S3) bucket. Then, launch the templates directly from the S3 bucket. This practice lets you control when to apply the latest changes to your environment.

Clone a local copy of the Quick Start templates (including all of its submodules). From the command line, run:
```
git clone --recurse-submodules https://github.com/aws-quickstart/quickstart-atlassian-bitbucket.git
```

(Optional) The Quick Start templates repository uses the directory structure required by the Quick Start interface. If needed (for example, to minimize storage costs), you can remove all other files except the following:

quickstart-atlassian-bitbucket
├── submodules
├── quickstart-atlassian-services
│   └── templates
│       └── quickstart-vpc-for-atlassian-services.yaml
└── templates
    ├── quickstart-bitbucket-dc-with-vpc.template.yaml
    └── quickstart-bitbucket-dc.template.yaml

Install and set up the AWS Command Line Interface (CLI) so that you can create an S3 bucket and upload content to it.

Create an S3 bucket in your Region:

aws s3 mb s3://<BUCKET_NAME> --region <AWS_REGION>

Choose which Quick Start template to use:
- quickstart-bitbucket-master-with-vpc.template.yaml: Use this template for deploying Bitbucket into a new ASI (end-to-end deployment).
- quickstart-bitbucket.template.yaml: Use this template for deploying Bitbucket into an existing ASI.
In both templates, the QSS3BucketName default value is set to aws-quickstart. Replace this value with the name of the bucket you created earlier (<BUCKET_NAME>).
Return to the parent directory of your local clone of the Quick Start templates. From there, upload all the files in your local clone to your S3 bucket:
```
aws s3 cp quickstart-atlassian-bitbucket s3://<BUCKET_NAME> --recursive --acl public-read
```

After everything is uploaded, you can deploy your production stack from your S3 bucket.

Sign in to your AWS account on the AWS Console.
Check the AWS Region displayed in the upper-right corner of the navigation bar, and change it if necessary. This Region is where {product-partner-name-short} is built. The template is launched in the us-east-2 Region by default.
Go to CloudFormation > Create Stack. When specifying a template, paste in the Object URL of the Quick Start template that you are using for the deployment. Choose Next to start configuring your deployment.

On the Specify stack details page, change the stack name, if needed. Review the parameters for the template, and provide values for parameters that require input. For all other parameters, review the default settings and customize them as necessary. For details about each setting, refer to the section matching your deployment type:

[launch-into-a-new-vpc] (if you’re deploying an ASI with Bitbucket)

[launch-into-an-existing-vpc] (if you’re deploying Bitbucket into a new ASI)

In the following tables, parameters are listed by category and described separately for the deployment options. When you finish reviewing and customizing the parameters, choose Next.

Unless you are customizing the Quick Start templates for your own deployment projects, keep the default settings for the parameters Quick Start S3 bucket name, Quick Start S3 bucket Region, and Quick Start S3 key prefix. Changing these settings automatically updates code references to point to a new Quick Start location. For more information, see the AWS Quick Start Contributor’s Guide.

On the Review page, review and confirm the template settings. Under Capabilities, select the two check boxes to acknowledge that the template creates IAM resources and might require the ability to automatically expand macros. . Choose Create stack to deploy the stack. . Monitor the status of the stack. When the status is CREATE_COMPLETE, the Bitbucket deployment is ready. . To view the created resources, see the values displayed in the Outputs tab for the stack.

Deploy with Control Tower

You can deploy Bitbucket in a customized AWS Control Tower environment to help you set up a secure, multi-account AWS environment using AWS best practices. For details, see Customizations for AWS Control Tower.

The root directory of the Bitbucket Quick Start repo includes a ct folder with a manifest.yaml file to assist you with the AWS Control Tower deployment. This file has been customized for the Bitbucket Data Center Quick Start.

In the following sections, you will review and update the settings in this file and then upload it to the S3 bucket that is used for the deployment.

Review the manifest.yaml file

Navigate to the root directory of the Bitbucket Quick Start, and open the manifest.yaml file, located in the ct folder.
Confirm that the region attribute references the Region where AWS Control Tower is deployed. The default Region is us-east-1. You will update the regions attribute (located in the resources section) in a later step.
Confirm that the resource_file attribute points to the public S3 bucket for the Bitbucket Data Center Quick Start. Using a public S3 bucket ensures a consistent code base across the different deployment options.

If you prefer to deploy from your own S3 bucket, update the path as needed.
Review each of the parameters attributes and update them as needed to match the requirements of your deployment.
Confirm that the deployment_targets attribute is configured for either your target accounts or organizational units (OUs).
For the regions attribute, add the Region where you plan to deploy the Bitbucket Quick Start. The default Region is us-east-1.

Upload the manifest.yaml file

Compress the manifest.yaml file and name it custom-control-tower-configuration.zip.
Upload the custom-control-tower-configuration.zip file to the S3 bucket that was created for the AWS Control Tower deployment (custom-control-tower-configuration-<accountnumber>-<region>).

The file upload initiates the customized pipeline that deploys the Quick Start to your target accounts.

Configuring Bitbucket

The following procedure helps you set up your new Bitbucket deployment.

Choose the URL that is displayed in the Outputs tab of the AWS CloudFormation stack to go to the Bitbucket configuration page.

If you get an HTTP Error 503 response when you access the URL, it means that Bitbucket is still loading. This is expected, and you should wait a couple of minutes before trying again.
On the Licensing and Settings page, enter a title for your Bitbucket deployment. Leave the base URL unchanged, and choose the appropriate licensing option. If you don’t have a valid license for Bitbucket Data Center, sign up for an evaluation license.

Figure 3. Licensing and settings
To set up Bitbucket Data Center, you need to create an Administrator account and password. The Administrator account has full access to all data in Bitbucket, so we highly recommend that you choose a strong password for this account. Enter your Administrator’s user details in the Administrator account setup screen, and choose Go to Bitbucket.

Figure 4. Administrator account setup
Log in with the user name and credentials you created in the previous step.

Figure 5. Log in
Choose > Clustering. You should see the Figure 6 page, which shows that your cluster has one node.

Figure 6. Clustering (one node)

Your Bitbucket Data Center deployment is now in a state where you can add nodes that will automatically cluster with your existing node.

Adding nodes to the Bitbucket cluster

By default, your Quick Start deployment starts with a single Bitbucket node (Auto Scaling group of min=1 and max=1). When you’re ready to add nodes to your cluster, perform the following steps:

Sign in to the AWS Management Console, use the Region selector in the navigation bar to choose the AWS Region for your deployment, and open the AWS CloudFormation console at https://console.aws.amazon.com/cloudformation/.
Choose the Bitbucket stack. From the Actions list, choose Update Stack.
On the Select Template page, leave Use current template selected, and then choose Next.
On the Specify Details page, in the Bitbucket Setup section of Parameters, enter the number of cluster nodes in Minimum number of cluster nodes and Maximum number of cluster nodes, and then click through to update the stack. This step sets a static number of nodes in your cluster.
After the stack finishes updating, verify the number of nodes in your Bitbucket cluster. Choose Clustering again from the administration console sidebar. The following example shows a cluster that is scaled up to three instances.

Figure 7. Clustering (multiple nodes)

You can also migrate Bitbucket data from an existing deployment to this one. For more information, see the migration guides on the Atlassian website.

Troubleshooting

Q. I encountered a CREATE_FAILED error when I launched the Quick Start.

A. If AWS CloudFormation fails to create the stack, relaunch the template with Rollback on failure set to Disabled. (This setting is under Advanced in the AWS CloudFormation console on the Options page.) With this setting, the stack’s state is retained and the instance is left running, so you can troubleshoot the issue. (Review the log files in /var/log/atl.log and /var/log/cfn-init.log.)

When you set Rollback on failure to Disabled, you continue to incur AWS charges for this stack. Ensure that you delete the stack when you finish troubleshooting.

For additional information, see Troubleshooting AWS CloudFormation on the AWS website.

Q. I encountered a size limitation error when I deployed the AWS CloudFormation templates.

A. Launch the Quick Start templates from the links in this guide or from another S3 bucket. If you deploy the templates from a local copy on your computer or from a location other than an S3 bucket, you might encounter template size limitations. For more information about AWS CloudFormation quotas, see the AWS documentation.
