Specs is a high level dashboard for viewing your ECS clusters. For a more complete description, see the blog post.
Specs can quickly show you:
- the services a given cluster is running
- the desired count of a given service
- the tagged docker image running
- the most recent events of a service
We built Specs to work around the sluggishness of the internal AWS dashboard. It allows for quick searching, and doesn't require paging through results. And if you run it internally, your teammates won't need any separate IAM users or permissions.
It's easiest to run Specs with docker. Assuming you have your AWS credentials exported, simply run the container like this:
$ docker run \
-e "AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID" \
-e "AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY" \
-e "AWS_REGION=$AWS_REGION" \
-e "AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN" \
-p 3000:3000 \

In order to run Specs, you'll need to create an IAM user or role with the following permissions:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"ecs:Describe*",
"ecs:DiscoverPollEndpoint",
"ecs:List*",
"ecs:Poll"
],
"Effect": "Allow",
"Resource": "*"
}
]
}
Then you should be off to the races.
To develop, you'll first need to install node. Then, you can run the server and client builders, both of which will watch for changes and hot-reload.
Run the server and client (with has your AWS credentials exported) with the following:
$ npm run dev
If you encouter this error: ConfigError: Missing region in config you will need to provide a default config environment or set the AWS_REGION environment variable like the following:
$ AWS_REGION=us-east-1 npm run dev
Now visit http://localhost:3001/ =)
