Cribl Edge as a Sidecar Container in AWS ECS

You can use Cribl Edge to collect logs from a service or task running in ECS. This is an alternative to forwarding logs to CloudWatch Logs.

Currently, you can’t configure Windows hosts as sidecar containers in AWS.

Container Definition
​

Add a secondary container to the task definition. To configure the container, you must first set the following environment variables:

NameValue
CRIBL_DIST_LEADER_URLtcp://<token>@<leader>:4200
CRIBL_DIST_MODEmanaged-edge
CRIBL_EDGE1
Add Environment Variables to Container Details
Add Environment Variables to Container Details

Configure Storage
​

To pass logs between containers, you can use a Bind Mount, which is a special folder mounted between containers. For details, see Using Data Volumes in Tasks.

Here’s an example configuration from the ECS task definition:

Sample JSON Container Definitions
​

You can adapt the following sample JSON definitions for the container. Note, this is not a full ECS task definition.
