Common Scaleway Issues and Solutions

1. Instance Deployment Failures

Instances fail to deploy or remain stuck in the "Provisioning" state.

Root Causes:

Insufficient available resources in the selected region.
Incorrect security group or firewall settings.
Invalid SSH key configuration.

Solution:

Check the availability of resources in the region:

scw instance server list

Ensure your security group allows inbound SSH traffic:

scw instance security-group list

Verify that your SSH key is correctly configured:

cat ~/.ssh/id_rsa.pub

If an instance is stuck in provisioning, try force-deleting it:

scw instance server terminate INSTANCE_ID

2. Network Connectivity Issues

Instances cannot connect to the internet or other internal services.

Root Causes:

Misconfigured private/public IP settings.
Firewall rules blocking traffic.
Incorrect DNS resolution.

Solution:

Check the assigned public and private IP addresses:

scw instance server get INSTANCE_ID

Ensure outbound traffic is allowed in the firewall settings:

scw instance security-group list-rules

Test internet connectivity using ping:

ping 8.8.8.8

If DNS resolution is failing, manually update /etc/resolv.conf:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf

3. API Authentication and Access Issues

API requests fail with authentication errors or permission issues.

Root Causes:

Expired or incorrect API credentials.
Insufficient permissions for the API key.
Incorrect API endpoint usage.

Solution:

Verify the API key is correctly set:

export SCW_ACCESS_KEY=your_access_keyexport SCW_SECRET_KEY=your_secret_key

Check the API key permissions:

scw iam api-key list

Ensure you are using the correct API endpoint:

scw instance server list --region=fr-par

4. Kubernetes Cluster Failures

Kubernetes clusters fail to deploy or worker nodes become unreachable.

Root Causes:

Incorrect networking setup for the cluster.
Insufficient worker node resources.
Control plane connectivity issues.

Solution:

Check the status of the cluster:

scw k8s cluster get CLUSTER_ID

Ensure worker nodes are properly registered:

kubectl get nodes

Restart any unresponsive nodes:

scw instance server reboot NODE_ID

If a node is unreachable, force-delete and replace it:

scw instance server terminate NODE_ID

5. Storage Performance and Access Issues

Block storage volumes are slow, or instances cannot mount volumes.

Root Causes:

Unoptimized disk performance settings.
Incorrect volume attachment to instance.
Filesystem corruption or mounting errors.

Solution:

Check storage volume attachment:

scw instance volume list

Ensure the volume is correctly mounted:

sudo mount /dev/vdb /mnt

Optimize storage performance using the correct filesystem:

sudo mkfs.ext4 /dev/vdb

Run a filesystem check if corruption is suspected:

sudo fsck -y /dev/vdb

Best Practices for Scaleway Cloud Management

Deploy instances in different availability zones for redundancy.
Use security groups and firewall rules to protect network access.
Regularly rotate API keys and review access permissions.
Monitor resource usage and scale Kubernetes clusters appropriately.
Backup important data using Scaleway Object Storage.

Conclusion

By troubleshooting instance deployment failures, networking problems, API authentication issues, Kubernetes cluster failures, and storage performance bottlenecks, users can effectively manage their cloud infrastructure on Scaleway. Implementing best practices ensures optimal performance, security, and scalability.

FAQs

1. Why is my Scaleway instance stuck in "Provisioning"?

Check resource availability, security group settings, and SSH key configuration. If necessary, force-delete the instance and redeploy.

2. How do I fix network issues on my Scaleway instance?

Verify IP settings, check firewall rules, and manually update DNS settings in /etc/resolv.conf.

3. What should I do if my API requests fail with authentication errors?

Ensure API credentials are set correctly, check permissions, and confirm the correct API endpoint is being used.

4. Why is my Kubernetes cluster not working properly?

Check cluster status, ensure worker nodes are registered, and restart or replace unresponsive nodes if necessary.

5. How can I improve storage performance on Scaleway?

Optimize disk performance settings, verify volume attachments, and use the correct filesystem format for better efficiency.
