問題緣由

本來是 docker 虛擬機運行著好好的绰垂，突然報錯：

Unable to query docker version: Get https://192.168.99.100:2376/v1.15/version: x509: certificate has expired or is not yet valid

很顯然可以看到certificate has expired字樣堕担，網上查了半天沛豌，docker-machine regenerate-certs和docker-machine provision命令都試過了，沒有作用棺榔。還有人說重建虛擬機夫晌，想想應該一定是有作用，但是里面的東西都要重建曙博，很麻煩。發(fā)現docker-machine ssh是正常的怜瞒，那就干脆 ssh 到虛擬機里面去操作父泳。

docker虛擬機里面沒有docker-compose，那就裝一個盼砍，倒也不麻煩。按照官方的指導逝她，兩個命令搞定

sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

接下來的麻煩

后來才意識到浇坐，docker虛擬機重啟以后，就要重新安裝docker-compose黔宛，它這個虛擬機是不保留狀態(tài)的呀近刘！這一長串的命令，就只好記到我的 commands.txt 里面去臀晃，每次用的時候去找出來復制粘貼（我把常用的命令什么的都記在這個文件中觉渴，加上 Sublime ，基本還是能很快找到想要用的命令）徽惋。

另外一個事案淋，許多容器沒設置成自動啟動，虛擬機重啟以后险绘，需要一一去啟動踢京，也是一樣誉碴，記下來，用的時候找出來復制粘貼瓣距。

docker-compose -f /Users/mike/Projects/docker/mysql/docker-compose.yml restart
docker-compose -f /Users/mike/Projects/docker/redis/docker-compose.yml restart
docker-compose -f /Users/mike/Projects/docker/www1/docker-compose.yml restart
docker-compose -f /Users/mike/Projects/docker/www2/docker-compose.yml restart
docker-compose -f /Users/mike/Projects/docker/myadmin/docker-compose.yml restart
docker-compose -f /Users/mike/Projects/docker/nginx/docker-compose.yml restart

解決復制粘貼命令的煩惱

最近開始用 flashops 黔帕，立馬想到，這些命令都弄到 flashops 里面去蹈丸。有個小問題成黄，就是得把 docker 虛擬機的 ssh 證書找出來，直接上結果逻杖，在這里：

/Users/mike/.docker/machine/machines/default/id_rsa

先上一下 flashops 配置

servers:
  - title: Docker Machine Default
    ssh:
      host: 192.168.99.100
      user: docker
      keyfile: /Users/mike/.docker/machine/machines/default/id_rsa
    operations:
      - title: Install Docker-Compose
        commands:
          - 'sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose'
          - 'sudo chmod +x /usr/local/bin/docker-compose'
      - title: Start all container
        commands:
          - 'docker-compose -f /Users/mike/Projects/docker/mysql/docker-compose.yml restart'
          - 'docker-compose -f /Users/mike/Projects/docker/redis/docker-compose.yml restart'
          - 'docker-compose -f /Users/mike/Projects/docker/www1/docker-compose.yml restart'
          - 'docker-compose -f /Users/mike/Projects/docker/www2/docker-compose.yml restart'
          - 'docker-compose -f /Users/mike/Projects/docker/myadmin/docker-compose.yml restart'
          - 'docker-compose -f /Users/mike/Projects/docker/nginx/docker-compose.yml restart'
          - 'docker ps'

再看一下整個執(zhí)行過程

比起到 commands.txt 里去找命令、復制粘貼舒服多了弧腥。

最后

再說一下 docker 虛擬機證書的問題厦取，最后我還是重建了 docker 虛擬機（重建里面的容器什么的倒是容易的，就是導入數據庫太慢管搪，電腦不給力啊虾攻，足足等了一個多小時）。
