Edge Services Batch Installation Docker Mode

Based on the ECP platform deployed by Docker, if the hardware of the edge service supports the deployment of Docker containers, edge services can be installed in batches on the ECP platform, shortening the installation and deployment time of edge services, and improving deployment efficiency and consistency.

Prerequisites

Before batch installation of edge services, you need to complete the following preparations:

  • Add edge node, the edge service will be installed on the edge node

Configuration Docker Environment

edge service is deployed by Docker, so you need to install Docker on the edge node.

After the installation is complete, you need to open the remote access port of the Docker API. The ECP platform manages the life cycle of the edge service through the Docker API, and supports two modes of Docker API to enable TLS authentication and not enable TLS authentication.

Do not enable TLS authentication

  1. Find the docker service configuration file, the default is: /usr/lib/systemd/system/docker.service, you can see the location of the file through the systemctl status docker command. docker_service
  2. Modify the ExecStart parameter and add parameters as shown below:
    shell
      ExecStart=/usr/bin/dockerd  -H fd:// --containerd=/run/containerd/containerd.sock  -H=0.0.0.0:2376
    execstart_no_tls
  3. Restart the docker service
    shell
    systemctl daemon-reload && systemctl restart docker
  4. Configure Docker connection configuration without TLS authentication method on ECP docker_mode1

Enable TLS authentication

  1. If the Docker API enables TLS authentication, the edge node deployed as the server needs to configure the CA certificate, server certificate and server private key of the Docker API. ECP as the client needs to configure the CA certificate, client certificate and client private key of the Docker API. For specific configuration methods, please refer to Docker TLS authentication.

    1. You can download the certificate file and script from this link

    Note

    This certificate is for testing only. Please use a self-signed certificate in a production environment.

    1. Modify the IP address in extfile.cnf to the IP address exposed by the edge node that deploys the Docker Engine service externally. This IP address is also the IP address that needs to be entered in ECP when adding edge nodes. extfile
    2. Execute the gen-docker-cert.sh script to generate the server certificate: server-cert.pem, the default password: 1111; gen-docker-cert
    3. Copy the generated server-cert.pem certificate file and ca.pem, server-key.pem files to the specified directory of the edge node, such as: /root/docker-tls/ca.pem, /root/docker-tls/server-cert.pem, /root/docker-tls/server-key.pem directory.
  2. Find the docker service configuration file, the default is: /usr/lib/systemd/system/docker.service, you can see the location of the file through the systemctl status docker command. docker_service

  3. Modify the ExecStart parameter and add parameters as shown below:

    shell
      ExecStart=/usr/bin/dockerd  -H fd:// --containerd=/run/containerd/containerd.sock  --tlsverify --tlscacert=/root/docker-tls/ca.pem --tlscert=/root/docker-tls/server-cert.pem --tlskey=/root/docker-tls/server-key.pem -H=0.0.0.0:2376

    exectart_tls

  4. Restart the docker service

    shell
    systemctl daemon-reload && systemctl restart docker
  5. Configure Docker connection configuration with TLS authentication method on ECP upload the certificate file ca.pem, cert.pem, key.pem to ECP. docker_mode2

Batch Install Edge Services

  1. Log in as system admin, organization admin, or project admin. Navigate to Workspace - Edge Service page.

  2. Click the Add Edge Service button to enter the Add Edge Service page.

  3. Choose Install new Services in batches for Add Type, choose docker type for Batch Installation Type.

  4. For Category, now only NeuronEX.

  5. Connection Type is set to Direct by default and cannot be changed.

  6. Enter the name prefix of the edge service, and the system will automatically generate a unique service name based on the name prefix; 1-20 characters, and supports "-" and spaces.

  7. Select one or more edge nodes, and ECP will deploy an edge service instance of the selected type on each edge node.

  8. Set the configuration parameters of the edge service. If not modified, the parameters in the global configuration will be used by default.

  9. Select the image where the edge service needs to be installed.

  10. [Optional] Install the NeuronEX instance and choose whether to enable authentication. For detailed information, please view Edge Service Authentication.

  11. [Optional] You can choose to add labels to edge service instances to facilitate subsequent maintenance.

  12. ECP will automatically generate an information overview of this installation on the right side of the page based on the above settings. You can confirm it here. If the information is confirmed, you can click the Confirm button to install batch edge services.

批量安装边缘服务

Check the installation progress

After clicking Confirm, the batch installation results dialog box will pop up, you can view it here:

  • Statistics on total number of installations, number of successful installations, number of failed installations and ongoing installations;
  • For installation failures, you can view the reason for the installation failure in the Cause column;

Batch installation-execution results

Click Back to return to the Edge Services page, and the newly installed edge service will appear in the Edge Services section of the page.

In addition, ECP will record all the information of this batch installation, and the system/organization/project administrator can view it in Operation Audit.

TIP

For usage restrictions on batch installation, please refer to System Usage Limitations and Version Compatibility Limitations.
