CleanStart Container for Curl

Enterprise-grade containerized curl client for secure and efficient HTTP/HTTPS requests. This image provides the popular curl command-line tool for transferring data using various protocols, optimized for cloud-native environments. Built on a security-hardened base, it includes SSL/TLS support, comprehensive protocol handling (HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, DICT, TELNET, LDAP, FILE), and enterprise security features including FIPS compliance options. Ideal for automated testing, API interactions, and secure file transfers in containerized environments.

Security & Best Practices

Recommended Security Context

yaml
securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  readOnlyRootFilesystem: true
  allowPrivilegeEscalation: false
  capabilities:
    drop: ['ALL']

Best Practices

• Use specific image tags for production (avoid latest)
• Configure resource limits: memory and CPU constraints
• Enable read-only root filesystem when possible
• Run containers with non-root user (--user 1000:1000)
• Use --security-opt=no-new-privileges flag
• Regularly update container images for security patches
• Implement proper network segmentation
• Monitor container metrics for anomalies

Architecture Support

Multi-Platform Images

bash
  docker pull --platform linux/amd64 cleanstart/curl:latest
docker pull --platform linux/arm64 cleanstart/curl:latest
