如何在啓動Docker時連接到當前容器？

基本上，我想通過使用mongodump和mongorestore將其與Docker一起旋轉後初始化一個mongo數據庫。 mongorestore失敗，因爲它無法連接到容器的主機名。任何幫助，將不勝感激。我試過localhost，而且它也不起作用。如何在啓動Docker時連接到當前容器？

我Dockerfile：

FROM mongo 

RUN mongodump --host merchdev02.bcinfra.net --port 27017 --db ap 
RUN mongorestore --host $(hostname) --port 27017 --db ap

錯誤：

A Docker command executed by Vagrant didn't complete successfully! 
The command run along with the output from the command is shown 
below. 

Command: "docker" "build" "/mnt/docker_build_52c7cc3c5608022927f471820455e02b"

我用流浪來引導多克。我Vagrantfile：

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

最後我的主機VM的Docker容器使用方法：

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

你試過'mongorestore --host 127.0.0.1 --port 27017 --db ap'嗎？ – 2014-09-12 17:01:58

@ BenWhaley是的。沒有運氣。 – 2014-09-12 17:56:05

你確定Mongo正在運行嗎？我不認爲這會是，它在Dockerfile – 2014-09-12 18:00:15

蒙戈容器套的mongod作爲其命令CMD["mongod"]這意味着它不運行，直到你真正做docker run ...

我通常總是在腳本容器中包含一個腳本ADD init.sh來處理任何在構建時沒有意義的配置任務。

init.sh會自動執行還是必須添加CMD才能在啓動時運行它？ – 2014-09-12 19:10:08

您必須添加CMD – 2014-09-12 20:29:31
