启动Docker时如何连接到当前容器？
基本上，我试图通过使用mongodump和mongorestore使用Docker将其转换为初始化mongo数据库。 mongorestore失败，因为它无法连接到容器的主机名。 任何帮助，将不胜感激。 我已经尝试了localhost ，而且也不起作用。
我的Dockerfile：
FROM mongo RUN mongodump --host merchdev02.bcinfra.net --port 27017 --db ap RUN mongorestore --host $(hostname) --port 27017 --db ap
错误：
A Docker command executed by Vagrant didn't complete successfully! The command run along with the output from the command is shown below.

我正在使用Vagrant来引导Docker。 我的stream浪文件：
VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.provider "virtualbox" do |v| v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"] end # Setup docker config.vm.define "mongo" do |v| v.vm.synced_folder "logs", "/var/log/mongodb" v.vm.provider "docker" do |d| d.vagrant_vagrantfile = "../host-vm/Vagrantfile" d.build_dir = "." d.ports = ['27017:27017'] d.remains_running = true d.name = "mongo" end end end
最后，我的主机虚拟机的Docker容器使用：
VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "hashicorp/precise64" config.vm.provision "docker" config.vm.provision "shell", inline: "ps aux | grep 'sshd:' | awk '{print $2}' | xargs kill" config.vm.network :forwarded_port, guest: 27017, host: 27017 end
mongo容器将mongod设置为它的命令CMD["mongod"] ，这意味着它不会运行，直到您实际执行docker run ...
我通常总是在我的ADD init.sh容器中包含一个脚本ADD init.sh来处理任何在构build时没有意义的configuration任务。
