Auth and Proxy Configuration

Upgrade Teleport's connection limits from the default connection limit of 15000 to 65000.

# Teleport Auth and Proxy
    max_connections: 65000
    max_users: 1000

Kernel parameters

Tweak Teleport's systemd unit parameters to allow a higher amount of open files:


Verify that Teleport's process has high enough file limits:

cat /proc/$(pidof teleport)/limits

Limit Soft Limit Hard Limit Units

Max open files 65536 65536 files

DynamoDB configuration

When using Teleport with DynamoDB, we recommend using on-demand provisioning. This allow DynamoDB to scale with cluster load.

For customers that can not use on-demand provisioning, we recommend at least 250 WCU and 100 RCU for 10k clusters.


When using Teleport with etcd, we recommend you do the following.

  • For performance, use the fastest SSDs available and ensure low-latency network connectivity between etcd peers. See the etcd Hardware recommendations guide for more details.
  • For debugging, ingest etcd's Prometheus metrics and visualize them over time using a dashboard. See the etcd Metrics guide for more details.

During an incident, we may ask you to run etcdctl, test that you can run the following command successfully.

etcdctl \

--write-out=table \

--cacert=/path/to/ca.cert \

--cert=/path/to/cert \

--key=/path/to/key.pem \

--endpoints= \
