ECS Connect

Seamlessly connect to containers running in ECS.

Requirements

EC2 Based

For EC2 based ECS deploymnets, you need SSM Session Manager enabled on the EC2 instances. For enabling SSM Sessions refer this.

Make sure you have set proper IAM permissions for the developer going to access containers deployed in EC2 using ecs-connect tool.

Fargate Based

For Fargate based ECS deploymnets, the SSM Session Manager can't be enabled directly as undelying EC2 instances are managed by AWS. So a Bastion node, an EC2 instances with SSM Session Manager enabled is required. For enabling SSM Sessions refer this.

Also, the SSHD must be installed on the container to which you want to connect. And you need to create SSH keys and place them in the container and the bastion node. To setup SSH keys refer this. Make sure you have placed SSH key in bastion node at home/ssm-user/bastion (where bastion is a key name)

Usage

ecs_connect --profile <profile> --cluster <cluster name> --service <service name> --cmd <init cmd>

Example

ecs_connect

If nothing is provided, then config will be pulled from default profile saved in ~/.ecs_connect config file.

Optional flags:

• --profile Name of the profile to use in ~/.ecs-connect. If none is provided, then the default profile will be used.
• --cluster Name of the ECS cluster.
• --service Name of the service.
• --task Started by name. If provided, the service will be ignored.
• --cmd Initilization command to run, will be executed once connected to container. If provided, then parameter from profile will be overridden.
• --all Displays all running containers, for ECS EC2 based running tasks/services.
• --verbose More verbose output.
• --debug Very verbose output. Useful for debugging.

Additional options available in only config file: * --ssh_user User name for ssh into fargate based service. * --ssh_key SSH key path on bastion node.

Note

• Set cmd to sh or bash depending on container os to get shell access.
• <service name> will be used to filter containers.
