Best Practices
Security Considerations
1. Use Service Accounts for Production: Never use personal accounts for production deployments
2. Rotate Credentials Regularly: Update service account keys periodically
3. Limit Permissions: Apply the principle of least privilege
4. Secure Key Storage: Store service account keys securely and never commit them to version control
```bash
Example: Create a service account with limited permissions
gcloud iam service-accounts create my-service-account \
--description="Service account for application X" \
--display-name="My Service Account"
Grant specific roles only
gcloud projects add-iam-policy-binding PROJECT_ID \
--member="serviceAccount:my-service-account@PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/storage.objectViewer"
```
Configuration Management
1. Use Named Configurations: Organize different environments with named configurations
2. Document Settings: Keep track of configuration choices
3. Version Control: Store configuration scripts in version control
```bash
Example configuration script
#!/bin/bash
gcloud config configurations create staging
gcloud config set project my-staging-project
gcloud config set compute/region us-west1
gcloud config set compute/zone us-west1-b
```
Automation and CI/CD
1. Non-Interactive Installation: Use flags for automated installations
2. Service Account Authentication: Use service accounts for CI/CD pipelines
3. Container Images: Consider using official Google Cloud SDK container images
```bash
Non-interactive installation example
curl https://sdk.cloud.google.com | bash -s -- --disable-prompts --install-dir=/opt
```
Maintenance
1. Regular Updates: Keep the SDK updated for latest features and security patches
2. Monitor Deprecations: Stay informed about deprecated features
3. Backup Configurations: Save important configuration settings
```bash
Automated update script
#!/bin/bash
echo "Updating Google Cloud SDK..."
gcloud components update --quiet
echo "Update completed: $(gcloud version --format='value(Google Cloud SDK)')"
```
Advanced Configuration
Custom Installation Locations
For system-wide installations:
```bash
Install to /opt directory
sudo mkdir -p /opt/google-cloud-sdk
sudo chown $USER:$USER /opt/google-cloud-sdk
curl https://sdk.cloud.google.com | CLOUDSDK_INSTALL_DIR=/opt bash
```
