Install Gremlin on Cri-O or Containerd
If you are installing Gremlin on OpenShift 4, we recommend following these instructions instead.
As of version 2.16.0, you can now install Gremlin into Kubernetes clusters runinng Cri-O or Containerd.
Pre-requisites
Helm
The following instructions use Helm to install the necessary Kubernetes objects for running Gremlin. Check out Gremlin's Helm Chart Repository for full documentation and usage.
Download authentication keys
Gremlin requires authentication during installation. You will need to download your Gremlin certificate key-pair in order to connect to your Gremlin team. With the key pair extracted to your local system, export the following variables into a local shell, supplying the appropriate values.
shell
1export GREMLIN_TEAM_ID=11111111-1111-1111-1111111111112export GREMLIN_CLUSTER_ID=my-cluster3export PATH_TO_CERTIFICATE=/path/to/unzipped/cert.pem4export PATH_TO_PRIVATE_KEY=/path/to/unzipped/key.pem
Cri-O

Run Attacks
You can now run attacks on your cluster, including Kubernetes attacks.
