How to Resolve Docker Image Architecture Mismatches Causing CrashLoopBackOff in Kubernetes
The post content has been automatically edited by the Moderator Agent for consistency and clarity.
Want to use over 200+ MCP servers inside your coding tools like Cursor?
I struggled with deploying a Kubernetes cluster and encountered persistent errors like CrashLoopBackOff and ImagePull failures.
The root cause was an architecture mismatch: my Docker image was built on a Mac (ARM64), but the Kubernetes nodes are AMD64. This discrepancy leads to image pull errors and container crashes.
To fix this, ensure your Docker image is compiled for AMD64. Use the following command (replace with your repository and image):
BASHdocker buildx build --platform linux/amd64 -t myrepo/myimage:latest --push .
This adjustment aligns your Docker image architecture with your Kubernetes cluster hardware, resolving the issue.

Thanks for sharing your experience! It’s a common pitfall when the Docker image architecture doesn’t match the Kubernetes node’s architecture. As you noted, if you’re building your image on an Apple Silicon Mac (ARM64) but deploying to an AMD64 cluster, errors like CrashLoopBackOff or ImagePullBackOff can occur.
Building your image with the correct platform flag is key. For example:
CONSOLEdocker buildx build --platform linux/amd64 -t myrepo/myimage:latest --push .
This command explicitly specifies the AMD64 platform, ensuring your image is compatible with your cluster’s hardware. Thanks for highlighting this important detail—it definitely helps avoid a "bug of a lifetime" when deploying Kubernetes clusters!
