- RegisterTaskDefinition rejects container secrets[] (InvalidParameterException)
and warns on unsupported log drivers instead of silently dropping them.
- Capture logConfiguration; only host-side json-file is collected, other drivers
warn at register and reach the agent for parity. Document json-file retrieval.
- Plumb executionRoleArn taskdef -> assign -> agent; the agent assumes it to
authorize ECR pulls, falling back to the instance role when unset.
- Add deployment objects with a health-gated rolling update honoring
deploymentConfiguration minimumHealthyPercent/maximumPercent, plus a deployment
circuit breaker with optional rollback to the last-good task definition.
* fix: free host-netns :80 for ECS bridge/host tasks via cred-endpoint DNAT
bridge and host network-mode tasks share the VM host netns where the
ecs-agent credential endpoint bound 169.254.170.2:80, so a task binding
0.0.0.0:80 hit EADDRINUSE and crash-looped. Bind the listener on the high
proxy port 51679 and DNAT 169.254.170.2:80 to it (OUTPUT for host/bridge
task traffic, PREROUTING for the awsvpc credential veth), keeping the dst
IP on the endpoint so no route_localnet is needed. Nothing holds a socket
on :80, so host/bridge tasks can bind it.
e2e runs nginx on :80 in all three network modes; the settle guard catches
a regression where a crash-looping :80 bind flaps RUNNING then STOPPED.
* test: validate ECS host-netns :80 binding via bridge task
The bridge subtest now runs nginx on :80 to prove the cred-endpoint DNAT
frees the host netns (pre-fix it crash-looped on EADDRINUSE). host mode
keeps a no-port command: it shares the same host netns, so two :80 tasks
cannot coexist on one node (one :80 per host, as on AWS), and StopTask
does not synchronously reap the prior container's port.
Serve task-role credentials to containers the AWS-faithful way: an HTTP
endpoint at 169.254.170.2:80 inside the ecs-agent (host VM netns) serving
short-lived credentials at /v2/credentials/{credID}. Containers find it via
AWS_CONTAINER_CREDENTIALS_RELATIVE_URI, injected per container.
The agent mints credentials by SigV4-signing sts:AssumeRole(taskRoleARN)
against the gateway with its instance-role credentials, mirroring
internal/ecrauth. This reconciles ecs-v1 Q4/Q10 (STS over NATS + scheduler
JWT assertion) with the 4f rewire that moved the agent entirely onto the
gateway: the agent has no NATS connection and already holds instance creds,
so it assumes the task role directly. Credentials are cached per credID and
refreshed near expiry.
Each awsvpc task netns gets a credentials veth into the host netns and a
host-routed /32 to the endpoint, keeping it off the task ENI's VPC route.
The scheduler now persists taskRoleArn on the task definition and carries it
in the assign payload so the endpoint activates end to end.
