Implementations provide for container clustering in a container-based architecture. A method of the disclosure includes generating by a processing device executing a container deploying an instance of an application image, a domain name server (DNS) query to request identification of other containers in a container cluster. The other containers deploy other instances of the application image. The method also includes in responsive to the DNS query, receiving the identification of each of the other containers in the container cluster. The method further includes configuring, without manual intervention, the container as a member of the container cluster in view of the identification of each of the other containers.
