Environment Preparation

Prepare a bare metal machine (the bare metal machine needs to be in a public network environment for building offline installation packages in online scenarios).

Note:
For bare metal configuration, please refer to the bootstrap node configuration information in the Configuration Requirements section above.
Ensure that this machine does not have the /bke directory.

Install tar, pigz, bkeadm, and Docker (use Docker version 20.10.13 or 18.09.0).

For tar tool installation version, please refer to https://mirrors.aliyun.com/gnu/tar/.
For pigz tool installation version, please refer to https://zlib.net/pigz/.

bkeadm can be downloaded and installed by executing the following commands.

# Method 1: Quick download
curl -sfL https://openfuyao.obs.cn-north-4.myhuaweicloud.com/openFuyao/bkeadm/releases/download/latest/download.sh | bash

# Method 2: Download with integrity verification
## Download download.sh script file
curl -LO https://openfuyao.obs.cn-north-4.myhuaweicloud.com/openFuyao/bkeadm/releases/download/latest/download.sh
## Download the checksum file for download.sh and verify (optional). Successful verification will output -: OK. If verification fails, contact openFuyao community maintainers to locate the cause
curl -LO https://openfuyao.obs.cn-north-4.myhuaweicloud.com/openFuyao/bkeadm/releases/download/latest/download.sh.sha256
sha256sum -c <(cat download.sh.sha256) < download.sh
## Run download.sh to download the bke installation tool, which will verify sha256sum during execution
chmod +x download.sh && ./download.sh

Installation Steps

Build deployment package.

1.1 After completing Docker installation, add the following configuration to the Docker configuration file.

Edit the /etc/docker/daemon.json file (create one if it doesn't exist).

 {
 "insecure-registries": [     
   "0.0.0.0/0"
 ]    
 }

1.2 Execute the following command to restart Docker.

 systemctl restart docker

1.3 Build offline installation deployment package.

Collect binary files, RPM packages, Chart packages, etc. and finally generate a compressed package. The offline-artifacts.yaml can be downloaded by clicking download. Determine the extension components to be installed, and open the download switch for the corresponding components in the yaml file (default is closed). Below shows enabling the volcano component image download switch. During subsequent offline installation package preparation, the images required by volcano will be downloaded.

  - architecture:  # openfuyao volcano extension component
      - amd64
      - arm64
    needDownload: true # Switch for whether to download images required by volcano extension component, false-off do not download, true-on download
    subImages:
      - sourceRepo: cr.openfuyao.cn/openfuyao
        targetRepo: openfuyao
        images:
          - name: volcano-config-website
            tag:
              - latest
          - name: volcano-config-service
            tag:
              - latest
          - name: numa-tuning-operator
            tag:
              - v25.03
          - name: volcano/resource-exporter
            tag:
              - latest
          - name: oauth-proxy
            tag:
              - latest
          - name: vc-scheduler
            tag:
              - latest
      - sourceRepo: docker.io
        targetRepo: /
        images:
          - name: volcanosh/vc-webhook-manager
            tag:
              - v1.9.0
          - name: volcanosh/vc-controller-manager
            tag:
              - v1.9.0

Execute the following command to build the offline installation deployment package.

Note: The duration is approximately 1 hour. Errors during the import process will have a retry mechanism; errors that do not terminate the process can be ignored.

rm -rf /bke && bke build -f offline-artifacts.yaml -t bke.tar.gz

Perform offline installation of bootstrap node.

Notice: The presence of container runtimes such as docker, containerd, or related system residual files on the bootstrap node will cause openFuyao's configuration for the container runtime to not take effect, resulting in installation failure. To ensure successful installation, it is recommended to use a fresh bare metal machine for installation.

2.1 Copy the deployment package from the online environment to the offline environment bootstrap node (operate according to actual situation).

2.2 Execute the following command to extract the deployment package to the root directory.
```
  rm -rf /bke && tar zxvf <deployment package name eg: bke.tar.gz> -C /
```
Note:
It is recommended that the root directory storage space be greater than 29GB after extraction, otherwise initialization will be affected.

Modify the BKE installation tool name and initialize the bootstrap node.

# Modify installation tool name
ARCH=$(uname -m)
case $ARCH in
x86_64) ARCH="amd64";;
aarch64) ARCH="arm64";;
esac
mv /usr/local/bin/bkeadm_linux_$ARCH /usr/local/bin/bke
# Initialize bootstrap node
bke init

Execute the following command to view the Pods deployed on the bootstrap cluster.
```
kubectl get pod -A
```
After all Pod states are normal, the bootstrap cluster installation is complete, and you can continue to log in to the openFuyao bootstrap node management plane for service cluster installation.

Uninstallation

Execute the following command to reset the bootstrap cluster.
```
bke reset --all --mount
```
Execute the following command to completely uninstall BKE related content.
```
rm -rf /bke
rm -f /usr/local/bin/bke
```
