## Prerequisites
|
|
|
|
1. Running docker environment on the server.
|
|
2. Domain name is mapped to the server IP address.

|
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.
