Local Docker installation

This page describes how to install OpenServerless on your local machine. The services are limited and not accessible from the outside so it is an installation useful only for development purposes.

Prerequisites

Before installing, you need to:

• install Docker.

• install ops.

• perform a minimal configuration. For more details about this, check Configure the services.

💡 NOTE

The static service works perfectly for the default namespace nuvolaris which is linking the http://localhost to the nuvolaris web bucket. With this setup adding new users will add an ingress with host set to namespace.localhost, that in theory could also work if the host file of the development machine is configured to resolve it to the 127.0.0.1 ip address.

⚠ WARNING

You cannot have https in a local installation. If you enable it, the configuration will be ignored.

Installation

Run the commands:

1. Minimal configuration

ops config minimal

Behind the scene, this command will write a cluster configuration file called ~/.ops/config.json activating these services: static, redis, postgres, ferretdb, minio, cron constituting the common baseline for development tasks.

2. Setup the cluster

ops setup devcluster

and wait until the command terminates.

ops setup devcluster
Creating cluster "nuvolaris" ...
 ✓ Ensuring node image (kindest/node:v1.25.3) 🖼
 ✓ Preparing nodes 📦 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
 ✓ Joining worker nodes 🚜
 ✓ Waiting ≤ 1m0s for control-plane = Ready ⏳
 • Ready after 1s 💚
Set kubectl context to "kind-nuvolaris"
You can now use your cluster with:

kubectl cluster-info --context kind-nuvolaris --kubeconfig /Users/bruno/.ops/tmp/kubeconfig

Thanks for using kind!

Troubleshooting

Usually the setup completes without errors.

However, if ops is unable to complete the setup, you may see this message at the end:

ops: Failed to run task "create": exit status 1
task execution error: ops: Failed to run task "create": exit status 1
ops: Failed to run task "devcluster": exit status 1
task execution error: ops: Failed to run task "devcluster": exit status 1

If this is your case, try to perform a uninstall / reinstall:

ops setup cluster --uninstall
ops config reset
ops config minimal
ops setup devcluster

If this will not solve, please contact the community.

Post install

Check the tutorial to learn how to use it.

Uninstall

To uninstall you may:

Uninstall devcluster

This will actually remove the ops namespace and all the services from kind. Useful to re-try an installation when something gone wrong.

ops setup cluster --uninstall
ops config reset

Remove devcluster

This will actually remove the nodes from kind:

ops setup devcluster --uninstall
