Summary#

Docker Compose is best treated as a single-host orchestration tool for a relatively fixed set of services. If a workload needs multi-host scheduling, platform-managed self-healing, rolling updates, autoscaling, cluster networking, or cluster-level policy, use Kubernetes or another cluster orchestrator instead. For image updates, do not assume docker compose restart will pick up a newer image: pull or build the image first, then recreate the affected containers.

Problem#

Teams sometimes use Docker Compose as if it were a Kubernetes-like cluster orchestrator, or they expect a restarted container to automatically run a newer image tag. Both assumptions create deployment drift: the stack may lack the scheduling and rollout behavior the workload requires, and a container may continue running an older image even after an image has been updated in a registry or rebuilt locally.

Guidance#

Use Docker Compose when: - The deployment target is one host. - The service graph is relatively stable. - The main goal is reproducible local development, CI integration testing, or a small single-server stack. - Manual or external operational procedures are acceptable for host failure, scaling, and rollout control.

Use Kubernetes or another orchestrator when: - Workloads must be scheduled across multiple nodes. - Replicas, rolling updates, self-healing, autoscaling, service discovery, ingress, namespaces/RBAC, or cluster-level resource policy are required. - Deployment failures such as image pull errors, scheduling failures, readiness/liveness failures, and rollout status must be handled through a standardized platform workflow.

For image refreshes in Compose: - Pull the new image (docker compose pull) or rebuild it (docker compose build / docker compose up --build) as appropriate. - Recreate the affected containers (docker compose up -d with the updated image, or an explicit recreate flow) rather than relying on a plain restart. - Avoid indiscriminate deletion of containers, volumes, or bind-mounted data. Recreate only the services that need the new image unless a broader migration is intentional.

Failure Modes#

  • Using Compose for workloads that require multi-host scheduling, elastic scaling, or orchestrator-managed failover.
  • Treating docker compose restart as an image update mechanism and leaving old containers running old image layers.
  • Assuming latest is enough to refresh runtime state without an explicit pull/build and container recreate.
  • Removing containers or volumes broadly and accidentally deleting stateful data or volume-backed resources.
  • Treating Compose deploy: or resource settings as Kubernetes-equivalent guarantees without checking the Compose implementation, Swarm mode, compatibility flags, and host cgroup behavior.
