Configuring the Local Repository and Image

Perform operations in this section on physical nodes.

1. Pull the local repository registry:2.

   podman pull docker.io/library/registry:2

   

   If you cannot access the external network, run the following commands or manually download the package and import it to the current node.

   git config --global http.sslVerify false
   git config --global https.sslVerify false
   git clone https://github.com/NotGlop/docker-drag.git

2. Start the local repository.

   podman load -i registry_2.tar

3. Modify the container configuration file /etc/containers/registries.conf.

   unqualified-search-registries = ["[IP]", "quay.io"]
   short-name-mode="enforcing"
   [[registry]]
   location = "[IP]:5000"
   insecure = true

   

   [IP] indicates the actual local IP address.

4. Modify the local repository settings.

   mkdir -p /home/registry-data
   podman run -d -p 5000:5000 -v /home/registry-data:/var/lib/registry --restart always --name registry localhost/registry:2

5. Import the Ceph deployment image generated in Creating a Deployment Image.

   podman load -i ceph_release.tar

6. Rename the image and upload it to the local repository.

   podman tag 8bbba7d5cc80 [IP]:5000/ceph/ceph_release:v17.2.7
   podman push [IP]:5000/ceph/ceph_release:v17.2.7 [IP]:5000/ceph/ceph_release:v17.2.7

   

   • 8bbba7d5cc80 indicates the image ID corresponding to ceph_release.tar, and [IP] indicates the local IP address. Replace them with the actual values.
   • If the gateway timeout error is reported during the push, check whether any proxy is configured. If yes, disable the proxy.

     unset http_proxy
     unset https_proxy

7. Modify DEFAULT_IMAGE in the cephadm file.

   vim /usr/sbin/cephadm
   yum install cephadm
   DEFAULT_IMAGE = "[IP]:5000/ceph/ceph_release:v17.2.7"

8. Modify the container creation permission (run_cmd function) in cephadm as follows:

   if self.privileged --> if self.privileged or not self.privileged

   

   

   • /usr/sbin/cephadm can be installed by configuring the Ceph 17 source or directly copying cephadm in the source code.
   • [IP] indicates the actual local IP address.
