Scalability tests

This repo collects code, instructions and results for scalability tests on the Rancher product family.

Usage

cd terraform
terraform init
terraform apply -auto-approve

npx cypress open --config watchForFileChanges=false

If you get this error from terraform apply:

│ Error: Kubernetes cluster unreachable: Get "https://upstream.local.gd:6443/version": dial tcp 127.0.0.1:6443: connect: connection refused

SSH tunnels might be broken. Reopen them via:

./config/open-tunnels-to-upstream-*.sh

In case Terraform returns an error with little context about what happened, use the following to get more complete debugging output:

export TF_LOG=debug

Use the following command to point to a remote Docker host:

export DOCKER_HOST=tcp://remotehost:remoteport

Note that the host has to have TCP socket enabled, in addition or replacing the default Unix socket.

Eg. on SUSE OSs edit the /etc/sysconfig/docker file as root and add or edit the following line:

DOCKER_OPTS="-H unix:///var/run/docker.sock -H tcp://127.0.0.1:2375"
