Prepare your Docker image with the NetOz deployment guide

Containers on NetOz run locked down for security, which is stricter than many published Dockerfiles expect. The Deployment guide in the NetOz Portal explains the rules and gives working examples you can copy into your repository.

Before you start

• Any team member can read the deployment guide.

Step 1 Open the Deployment guide

Choose Deployment guide under Hosting in the sidebar.

Step 2 Check the five rules

Your image must listen above port 1024, run as any user, write only to /tmp and its volumes, log to stdout and stderr and be built for linux/amd64. Breaking any of them usually shows up as a container that starts and immediately exits. Add a health path such as /healthz so deploys can switch traffic safely.

Step 3 Pick an example for your stack

Choose the tab closest to your application: Static site, Next.js server, Rails + React or WordPress. Volumes and mounts explains how to keep data that must survive a redeploy, such as uploads.

Step 4 Copy the files into your repository

Select Copy above each file and save it in the root of your repository. The notes under the examples list the container port, health path and memory to use when you set up the service.

Next steps

Once your Dockerfile follows the rules, push the image to your private registry and deploy it.
