+title: Setting up private docker registry for Compute-to-Data environment
+description: Learn how to setup own docker registry and push images for running algorithms in C2D environment.
+---
+
+## Prerequisites
+1. Running docker environment on the server.
+2. Domain name is mapped to the server IP address.
+3. SSL certificate
+
+## Step 1: Generate password file
+
+Replace content in `<>` with appropriate content.
+
+```bash
+docker run \
+  --entrypoint htpasswd \
+  httpd:2 -Bbn <username> <password> > <path>/auth/htpasswd
+```
+
+## Docker compose template file for registry
+
+Copy the below yml content to `docker-compose.yml` file and replace content in `<>`.
+
+```yml
+version: '3'
+
+services:
+  registry:
+    restart: always
+    container_name: my-docker-registry
+    image: registry:2
+    ports:
+      - 5050:5000
+    environment:
+      REGISTRY_HTTP_TLS_CERTIFICATE: /certs/domain.crt
+      REGISTRY_HTTP_TLS_KEY: /certs/domain.key
+      REGISTRY_AUTH: htpasswd
+      REGISTRY_AUTH_HTPASSWD_PATH: /auth/htpasswd
+      REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
+      REGISTRY_HTTP_SECRET: <secret>
+    volumes:
+      - <path>/data:/var/lib/registry
+      - <path>/auth:/auth
+      - <path>/certs:/certs
+
+```
+
+## Start the registry
+
+```bash
+docker-compose -f docker-compose.yml up 
+```
+
+## List images in the registry
+
+```bash
+curl -X GET -u <username>:<password> https://example.com/v2/_catalog
+```
+
+## Other useful commands
+
+
+## Login to registry
+
+```bash
+docker login example.com -u <username> -p <password>
+```
+
+## Build and push image to registry
+
+Use the commands below to build an image from a  `Dockerfile` and push to your own private registry.
+
+```bash
+docker build . -t example.com/my-algo:latest
+
+docker image tag example.com/my-algo:latest
+```
+
+## Next step
+
+You can publish an algorithm asset with the metadata containing registry url, image, and tag information to enable users to run C2D jobs.
