Jan 1, 2025January 2025 for srl-labs/containerlab focused on delivering interoperability improvements for SR Linux nodes, accelerating deployment workflows, and strengthening build/release hygiene. Notable work includes gRPC configuration support for SR Linux nodes in EDA, a redeploy command for quick rebuilds, stdin destruction support, and enhanced topology fidelity with SSH public keys exported under the topology JSON. We also implemented a centralized magic variable replacer and exec replacer to streamline templating, and advanced network policy handling for bridges using nftables/iptables. Default OpenConfig server enabled for 24.10+. Release engineering and maintenance tasks were completed to keep the project current and secure (version bumps to 0.63.x and release notes for 0.61.0, 0.62.0; removal of gomplate; SUID/NFPM hardening). Several stability and correctness fixes were addressed to reduce deployment risk and improve user experience across lab provisioning and topology generation.
