通过Akash Decloud部署去中心化的Bancor Web App

编译

下载 Bancor Web App

git clone https://github.com/bancorprotocol/webapp.git

然后进到 webapp 根目录依次执行命令

yarn install
yarn start

如果这里正确浏览器访问 http://localhost:8081/ 就可以访问 Bancor

然后执行命令打包应用

yarn build

成功打包之后的文件会放在 ./dist 目录下

创建 Docker 镜像

创建 Dockerfile 文件在里面添加一下内容

FROM nginx
COPY dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

之后打包镜像

docker build . -t bancor:latest

查看刚刚创建的镜像文件，确认刚刚打包的 bancor 镜像是否存在

docker images

创建并运行后台容器， 指定端口号 3257

docker run -d --name bancor -p 3257:80 --restart=unless-stopped bancor:latest

运行之后通过 http://localhost:3257 访问 Bancor

确认无误之后我们给刚刚的镜像打赏 TAG

docker tag bancor:latest sueinz/bancor:latest

之后我们上传前面生成的镜像到 Docker Hub

docker push sueinz/bancor:latest

通过 AKASH 部署 Bancor

这里参考部署教程，由于我们这个应用是个标准的 web 应用，我们直接参考官方教程部署

修改官方文件 deploy.yml文件，修改

services:
  web:
    image: lanakul/balancer:latest
    expose:
      - port: 80
        as: 80
        to:
          - global: true

为

services:
  web:
    image: sueinz/bancor:latest
    expose:
      - port: 80
        as: 80
        to:
          - global: true

然后执行命令部署

akash tx deployment create deploy.yml --from $KEY_NAME --node $AKASH_NODE --chain-id $AKASH_CHAIN_ID -y

得到如下输出

{
	"height": "149760",
	"txhash": "AC22B0BA0B466F759CEC6088205329811EF7C0494B916000C85376F81784AFB8",

	}],
	"info": "",
	"gas_wanted": "200000",
	"gas_used": "56891",
	"tx": null,
	"timestamp": ""
}

之后运行命令查看刚刚部署的状态

akash query market lease list --owner $ACCOUNT_ADDRESS --node $AKASH_NODE --state active

得到输出

leases:
- lease_id:
    dseq: "149758"
    gseq: 1
    oseq: 1
    owner: akash19uwxt0ln3p9fenpdwtsm5rlmqsekc3g9ym6xqz
    provider: akash1ds82uk3pzawavlasc2qd88luewzye2qrcwky7t
  price:
    amount: "235"
    denom: uakt
  state: active
pagination:
  next_key: null
  total: "0"

这里记录下前面的输出的几个变量备用

export PROVIDER=akash1ds82uk3pzawavlasc2qd88luewzye2qrcwky7t
export DSEQ=149758
export OSEQ=1
export GSEQ=1

然后上传 Manifest

akash provider send-manifest deploy.yml --node $AKASH_NODE --dseq $DSEQ --oseq $OSEQ --gseq $GSEQ --owner $ACCOUNT_ADDRESS --provider $PROVIDER

最后查看我们刚刚部署的具体信息

akash provider lease-status --node $AKASH_NODE --dseq $DSEQ --oseq $OSEQ --gseq $GSEQ --provider $PROVIDER --owner $ACCOUNT_ADDRESS

输出

{
  "services": {
    "web": {
      "name": "web",
      "available": 1,
      "total": 1,
      "uris": [
        "4ge79u689dd3d2qie2670bbjhg.provider5.akashdev.net"
      ],
      "observed-generation": 0,
      "replicas": 0,
      "updated-replicas": 0,
      "ready-replicas": 0,
      "available-replicas": 0
    }
  },
  "forwarded-ports": {}
}

然后访问 4ge79u689dd3d2qie2670bbjhg.provider5.akashdev.net 查看我们刚刚部署的应用程序，不出意外的话部署成功。
