You just pushed your latest branch to Bitbucket and your CI pipeline stalled again, waiting for credentials to deploy into Azure Kubernetes Service. No error, just a silent timeout while your token expired somewhere deep in an identity vault. Every DevOps engineer knows that feeling. Integrating Bitbucket with Microsoft AKS should feel like flipping a switch, not solving a mystery.
Bitbucket manages your source code and pipelines. Microsoft AKS runs your containers at scale. Together, they can deliver reliable, automated deployments to cloud infrastructure—if you get the identity and permissions story right. The magic happens when these two platforms talk securely, pass secrets cleanly, and know exactly who can do what.
Here’s how it works. Bitbucket Pipelines acts as your build and deploy engine. You provision an AKS cluster in Azure, then configure a service principal or managed identity that Bitbucket can use through an OpenID Connect (OIDC) trust. This removes static credentials from your pipeline. When a build runs, Bitbucket requests a short-lived token from Azure AD using OIDC, Azure verifies the request, then grants access scoped to just that workload. The token expires fast, leaving no long-term credentials behind.
Set role-based access control (RBAC) properly at the AKS level. Map your service principal to only the namespaces or resources it needs. Rotate identities automatically—prefer using Azure’s workload identity federation. Watch your audit logs from both Bitbucket and Azure for cross-references to keep compliance teams happy.
