Jan 1, 2026January 2026 (Month: 2026-01) monthly summary for aws/amazon-ecs-agent. The primary focus this month was delivering a DNS Configuration Enhancement for ECS Service Connect Tasks to improve network reliability and environment portability. The change uses the host's resolv.conf on ECS managed instances for DNS resolution, reducing reliance on the control plane and enabling more robust, adaptable network settings across environments. New functions were added to create and manage DNS configuration files to ensure ECS tasks receive correct DNS configuration.
