问题缘由
本来是 docker 虚拟机运行着好好的，突然报错：
Unable to query docker version: Get https://192.168.99.100:2376/v1.15/version: x509: certificate has expired or is not yet valid
很显然可以看到certificate has expired字样，网上查了半天，docker-machine regenerate-certs和docker-machine provision命令都试过了，没有作用。还有人说重建虚拟机，想想应该一定是有作用，但是里面的东西都要重建，很麻烦。发现docker-machine ssh是正常的，那就干脆 ssh 到虚拟机里面去操作。
docker虚拟机里面没有docker-compose，那就装一个，倒也不麻烦。按照官方的指导，两个命令搞定
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
接下来的麻烦
后来才意识到，docker虚拟机重启以后，就要重新安装docker-compose，它这个虚拟机是不保留状态的呀！这一长串的命令，就只好记到我的 commands.txt 里面去，每次用的时候去找出来复制粘贴（我把常用的命令什么的都记在这个文件中，加上 Sublime ，基本还是能很快找到想要用的命令）。
另外一个事，许多容器没设置成自动启动，虚拟机重启以后，需要一一去启动，也是一样，记下来，用的时候找出来复制粘贴。
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
解决复制粘贴命令的烦恼
最近开始用 flashops ，立马想到，这些命令都弄到 flashops 里面去。有个小问题，就是得把 docker 虚拟机的 ssh 证书找出来，直接上结果，在这里：
/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'
再看一下整个执行过程

比起到 commands.txt 里去找命令、复制粘贴舒服多了。
最后
再说一下 docker 虚拟机证书的问题，最后我还是重建了 docker 虚拟机（重建里面的容器什么的倒是容易的，就是导入数据库太慢，电脑不给力啊，足足等了一个多小时）。
