Amazon Elastic Container Service RPM

Amazon Elastic Container Service RPM

The Amazon Elastic Container Service RPM is software developed to support the Amazon ECS Container Agent. The Amazon ECS RPM is packaged for RPM-based systems that utilize Upstart as the init system.

Behavior

The upstart script installed by the Amazon ECS RPM runs at the completion of runlevel 3, 4, or 5 as the system starts. The script will clean up any previous copies of the Amazon ECS Container Agent, and then start a new copy. Logs from the RPM are available at /var/log/ecs/ecs-init.log, while logs from the Amazon ECS Container Agent are available at /var/log/ecs/ecs-agent.log. The Amazon ECS RPM makes the Amazon ECS Container Agent introspection endpoint available at http://127.0.0.1:51678/v1. Configuration for the Amazon ECS Container Agent is read from /etc/ecs/ecs.config. All of the configurations in this file are used as environment variables of the ECS Agent container. Additionally, some configurations can be used to configure other properties of the ECS Agent container, as described below.

Configuration Key	Example Value(s)	Description	Default value
ECS_AGENT_LABELS	{"test.label.1":"value1","test.label.2":"value2"}	The labels to add to the ECS Agent container.

Usage

The upstart script installed by the Amazon Elastic Container Service RPM can be started or stopped with the following commands respectively:

• sudo start ecs
• sudo stop ecs

Updates

Updates to the Amazon ECS Container Agent should be performed through the Amazon ECS Container Agent. In the case where an update failed and the Amazon ECS Container Agent is no longer functional, a rollback can be initiated as follows:

1. sudo stop ecs
2. sudo /usr/libexec/amazon-ecs-init reload-cache
3. sudo start ecs
