# Enable Docker Bridge Network
|
|
|
|
The latest versions of the AWS EKS-optimized AMI disable the docker bridge network by default. To enable it, add the `bootstrap_extra_args` parameter to your worker group template.
|
|
|
|
```hcl
|
|
locals {
|
|
worker_groups = [
|
|
{
|
|
# Other parameters omitted for brevity
|
|
bootstrap_extra_args = "--enable-docker-bridge true"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
Examples of when this would be necessary are:
|
|
|
|
- You are running Continuous Integration in K8s, and building docker images by either mounting the docker sock as a volume or using docker in docker. Without the bridge enabled, internal routing from the inner container can't reach the outside world.
