Setting Up Internet Access#

The Determined Docker images are hosted on Docker Hub. Determined agents need access to Docker Hub for such tasks as building new images for user workloads.
If packages, data, or other resources needed by user workloads are hosted on the public Internet, Determined agents need to be able to access them. Note that agents can be configured to use proxies when accessing network resources.
For best performance, it is recommended that the Determined master and agents use the same physical network or VPC. When using VPCs on a public cloud provider, additional steps might need to be taken to ensure that instances in the VPC can access the Internet:
- On GCP, the instances need to have an external IP address, or a GCP Cloud NAT should be configured for the VPC.
- On AWS, the instances need to have a public IP address, and a VPC Internet Gateway should be configured for the VPC.
