Bitbucket Mesh ¶
Bitbucket Mesh is a distributed, replicated, and horizontally scalable Git repository storage system, which increases performance and improves the resilience of Bitbucket.
You can learn more details about Bitbucket Mesh on the official documentation page.
Recommendations for Mesh deployments
Bitbucket version
By default, the Helm charts target the latest Bitbucket LTS version. However, Mesh is only supported from version 8.0. You will need to select an 8.x version of Bitbucket to deploy Mesh. Learn more details below.
Mesh agent version
Bitbucket Mesh agents are versioned independently from Bitbucket. You should select the appropriate version for the deployed version of Bitbucket. See the Mesh download page for available versions.
Number of Mesh nodes
In order for high-availability to be possible, we recommend having a minimum of three Mesh nodes. There is no maximum on the number of nodes.
Mesh node co-location
We don't currently support deploying Mesh nodes into multiple availability zones. Just like the shared file system based deployments, the Mesh nodes (that is, the repository storage) and the application nodes must be co-located.
Other Mesh deployment requirements
For more details on the requirements and limitations of Mesh deployments, check the the Bitbucket Mesh FAQ.
Configuring your Bitbucket and Mesh deployment ¶
For backwards compatibility, the Helm charts default to Mesh being disabled. To enable it, you will need to configure the service under bitbucket: stanza in the values.yaml file, substituting the values below from the above steps where appropriate:
image:
tag: <an 8.x.x version of Bitbucket>
bitbucket:
mesh:
enabled: true
image:
version: <Mesh agent version>
Adding the Mesh nodes to Bitbucket ¶
To enable the deployed Mesh nodes you need to add them to the Bitbucket Data Center instance in the administration area. To do so, you'll need the service URL of each node; these are usually of the form bitbucket-mesh-<num>. Check the Kubernetes official documentation to learn how to get a DNS record for a service.
To connect the Mesh node:
- In your Bitbucket Data Center instance, navigate to Administration > Git > Bitbucket Mesh.
- Enter the URL of the Mesh node in the Node URL field (e.g.
http://bitbucket-mesh-1:7777). - (Optional) Enter a name for the Mesh node in the Node name field.
- Select Add Mesh node.
