Consul使ってWindowsをリモートから操作する例

俺です。

consul execを使ってwindows powershellを叩く方法の例です。

consulが最も簡単にwindowsをリモート管理するツールな気がしました。

consul members

• Amazon Linuxをconsul serverとしてwindows(dev-win-1a)をjoinさせている

[ec2-user@ip-172-31-10-102 ~]$ consul members
Node           Address             Status  Type    Build  Protocol  DC
dev-win-1a     172.31.10.189:8301  alive   client  0.6.0  2         ap-northeast-1
prd-manage-1a  172.31.10.102:8301  alive   server  0.6.0  2         ap-northeast-1

config & startup

consul server(Linux)

• /home/ec2-user/conf/consul.json

{
    "server": true,
    "bootstrap_expect": 1,
    "bootstrap": false,
    "data_dir": "/home/ec2-user/data",
    "log_level": "INFO",
    "node_name":"prd-manage-1a",
    "datacenter":"ap-northeast-1"
}

• Amazon Linuxでconsul起動

[ec2-user@ip-172-31-10-102 ~]$ ./consul agent -config-dir=/home/ec2-user/conf

consul agent(Windows)

検証なのでWindows FirewallはOffってある

• c:¥consul¥conf¥consul.json

{
    "server": false,
    "bootstrap": false,
    "data_dir": "c:\\consul\\data\\",
    "log_level": "INFO",
    "node_name":"dev-win-1a",
    "datacenter":"ap-northeast-1"
}

• Windowsでconsul起動

PS C:\consul\bin> .\consul.exe agent -config-dir c:/consul/conf
==> Starting Consul agent...
==> Starting Consul agent RPC...
==> Consul agent running!
         Node name: 'dev-win-1a'
        Datacenter: 'ap-northeast-1'
            Server: false (bootstrap: false)
       Client Addr: 127.0.0.1 (HTTP: 8500, HTTPS: -1, DNS: 8600, RPC: 8400)
      Cluster Addr: 172.31.10.189 (LAN: 8301, WAN: 8302)
    Gossip encrypt: false, RPC-TLS: false, TLS-Incoming: false
             Atlas: <disabled>

==> Log data will now stream in as it occurs:

    2015/12/09 17:04:15 [INFO] serf: EventMemberJoin: dev-win-1a 172.31.10.189

consul join & members

• server側で実行

[ec2-user@ip-172-31-10-102 ~]$ ./consul join 172.31.10.189
[ec2-user@ip-172-31-10-102 ~]$ ./consul members
Node           Address             Status  Type    Build  Protocol  DC
dev-win-1a     172.31.10.189:8301  alive   client  0.6.0  2         ap-northeast-1
prd-manage-1a  172.31.10.102:8301  alive   server  0.6.0  2         ap-northeast-1

以上でconsulでWindowsを任意のホストからリモート管理できるようになった。

consul execの結果

• powershellワンライナー

[ec2-user@ip-172-31-10-102 ~]$ ./consul exec -node=dev-win-1a "powershell Write-Host hello"
    dev-win-1a: hello
    dev-win-1a:
==> dev-win-1a: finished with exit code 0

• powershellスクリプト

hello worldと出力するps1ファイルをWindows任意の場所に配置しておく

[ec2-user@ip-172-31-10-102 ~]$ ./consul exec -node=dev-win-1a "powershell c:/consul/helloworld.ps1"
    dev-win-1a: hello
    dev-win-1a:
==> dev-win-1a: finished with exit code 0
