+* 清理编译生成文件、安装包的缓存等临时文件; +* 安装各个软件时候要指定准确的版本号,并避免引入不需要的依赖; +* 从安全角度考虑,应用要尽量使用系统的库和依赖; +* 如果安装应用时候需要配置一些特殊的环境变量,在安装后要还原不需要保持的变量值; +* 使用 Dockerfile 创建镜像时候要添加 .dockerignore 文件或使用干净的工作目录。 + +### 碰到网络问题,无法 pull 镜像,命令行指定 http_proxy 无效? +答:在 Docker 配置文件中添加 `export http_proxy="http://:"`,之后重启 Docker 服务即可。 + +## 容器相关 +### 容器退出后,通过 docker ps 命令查看不到,数据会丢失么? +答:容器退出后会处于终止(exited)状态,此时可以通过 `docker ps -a` 查看。其中的数据也不会丢失,还可以通过 `docker start` 命令来启动它。只有删除掉容器才会清除所有数据。 + +### 如何停止所有正在运行的容器 +答:可以使用 `docker kill $(docker ps -q)` 命令。 + +### 如何清理批量后台停止的容器? +答:可以使用 `docker rm -f $(docker ps -qa)` 命令。 + +### 如何获取某个容器的 PID 信息? +答:可以使用 `docker inspect --format '{{ .State.Pid }}' ` 命令。 + +### 如何获取某个容器的 IP 地址? +答:可以使用 `docker inspect --format '{{ .NetworkSettings.IPAddress }}' ` 命令 + +### 如何给容器指定一个固定 IP 地址,而不是每次重启容器 IP 地址都会变? +答:目前 Docker 并没有提供直接的对容器 IP 地址的管理支持,用户可以考虑参考第三部分中高级网络配置章节中介绍的创建点对点连接例子,来手动配置容器的静态 IP。或者在启动容器后,再手动进行修改(可参考其它类的问题 “*如何进入 Docker 容器的网络命名空间?*”)。 + +### 如何临时退出一个正在交互的容器的终端,而不终止它? +答:按 `Ctrl-p Ctrl-q`。如果按 `Ctrl-c` 往往会让容器内应用进程终止,进而会终止容器。 + +### 使用 `docker port` 命令映射容器的端口时,系统报错“Error: No public port '80' published for xxx”? +答: + +* 创建镜像时 Dockerfile 要通过 EXPOSE 指定正确的开放端口; +* 容器启动时指定 `PublishAllPort = true`。 + +### 可以在一个容器中同时运行多个应用进程么? +答:一般并不推荐在同一个容器内运行多个应用进程。如果有类似需求,可以通过一些额外的进程管理机制,比如 supervisord 来管理所运行的进程。可以参考 https://docs.docker.com/articles/using_supervisord/。 + +### 如何控制容器占用系统资源(CPU、内存)的份额? +答:在使用 `docker create` 命令创建容器或使用 `docker run` 创建并启动容器的时候,可以使用 -c|--cpu-shares[=0] 参数来调整容器使用 CPU 的权重;使用 -m|--memory[=MEMORY] 参数来调整容器使用内存的大小。 + +## 仓库相关 +### 仓库(Repository)、注册服务器(Registry)、注册索引(Index) 有何关系? +首先,仓库是存放一组关联镜像的集合,比如同一个应用的不同版本的镜像。 + +注册服务器是存放实际的镜像文件的地方。注册索引则负责维护用户的账号、权限、搜索、标签等的管理。因此,注册服务器利用注册索引来实现认证等管理。 + +### 从非官方仓库(例如 non-official-repo.com)下载镜像时候,有时候会提示“Error: Invalid registry endpoint https://non-official-repo.com/v1/……”? +答:Docker 自 1.3.0 版本往后,加强了对镜像安全性的验证,需要添加私有仓库证书,或者手动添加对非官方仓库的信任。 +编辑 Docker 配置文件,在其中添加: + +```sh +DOCKER_OPTS="--insecure-registry non-official-repo" +``` +之后,重启 Docker 服务即可。 + +## 配置相关 +### Docker 的配置文件放在哪里,如何修改配置? +答:使用 upstart 的系统(如Ubuntu 14.04)的配置文件在 `/etc/default/docker`,使用systemd 的系统(如 Ubuntu 16.04、Centos 等)的配置文件在 `/etc/systemd/system/docker.service.d/docker.conf`。 + +Ubuntu 下面的配置文件内容如下,读者可以参考配。(如果出现该文件不存在的情况,重启或者自己新建一个文件都可以解决。) + +```sh +# Customize location of Docker binary (especially for development testing). +#DOCKERD="/usr/local/bin/dockerd" + +# Use DOCKER_OPTS to modify the daemon startup options. +#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4" + +# If you need Docker to use an HTTP proxy, it can also be specified here. +#export http_proxy="http://127.0.0.1:3128/" + +# This is also a handy place to tweak where Docker's temporary files go. +#export TMPDIR="/mnt/bigdrive/docker-tmp" +``` + +### 如何更改 Docker 的默认存储位置? +答:Docker 的默认存储位置是 `/var/lib/docker`,如果希望将 Docker 的本地文件存储到其他分区,可以使用 Linux 软连接的方式来完成,或者在启动 daemon 时通过 `-g` 参数指定。 + +例如,如下操作将默认存储位置迁移到 /storage/docker。 + +```sh +[root@s26 ~]# df -h +Filesystem Size Used Avail Use% Mounted on +/dev/mapper/VolGroup-lv_root 50G 5.3G 42G 12% / +tmpfs 48G 228K 48G 1% /dev/shm +/dev/sda1 485M 40M 420M 9% /boot +/dev/mapper/VolGroup-lv_home 222G 188M 210G 1% /home +/dev/sdb2 2.7T 323G 2.3T 13% /storage +[root@s26 ~]# service docker stop +[root@s26 ~]# cd /var/lib/ +[root@s26 lib]# mv docker /storage/ +[root@s26 lib]# ln -s /storage/docker/ docker +[root@s26 lib]# ls -la docker +lrwxrwxrwx. 1 root root 15 11月 17 13:43 docker -> /storage/docker +[root@s26 lib]# service docker start +``` + +### 使用内存和 swap 限制启动容器时候报警告:“WARNING: Your kernel does not support cgroup swap limit. WARNING: Your kernel does not support swap limit capabilities. Limitation discarded.”? +答:这是因为系统默认没有开启对内存和 swap 使用的统计功能,引入该功能会带来性能的下降。要开启该功能,可以采取如下操作: + +* 编辑 `/etc/default/grub` 文件(Ubuntu 系统为例),配置 `GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"`; +* 更新 grub:`$ sudo update-grub`; +* 重启系统,即可。 + +## Docker 与虚拟化 + +### Docker 与 LXC(Linux Container)有何不同? +答:LXC 利用 Linux 上相关技术实现了容器。Docker 则在如下的几个方面进行了改进: +* 移植性:通过抽象容器配置,容器可以实现从一个平台移植到另一个平台; +* 镜像系统:基于 AUFS 的镜像系统为容器的分发带来了很多的便利,同时共同的镜像层只需要存储一份,实现高效率的存储; +* 版本管理:类似于Git的版本管理理念,用户可以更方便的创建、管理镜像文件; +* 仓库系统:仓库系统大大降低了镜像的分发和管理的成本; +* 周边工具:各种现有工具(配置管理、云平台)对 Docker 的支持,以及基于 Docker的 PaaS、CI 等系统,让 Docker 的应用更加方便和多样化。 + +### Docker 与 Vagrant 有何不同? +答:两者的定位完全不同。 + +* Vagrant 类似 Boot2Docker(一款运行 Docker 的最小内核),是一套虚拟机的管理环境。Vagrant 可以在多种系统上和虚拟机软件中运行,可以在 Windows,Mac 等非 Linux 平台上为 Docker 提供支持,自身具有较好的包装性和移植性。 + +* 原生的 Docker 自身只能运行在 Linux 平台上,但启动和运行的性能都比虚拟机要快,往往更适合快速开发和部署应用的场景。 + +简单说:Vagrant 适合用来管理虚拟机,而 Docker 适合用来管理应用环境。 + +### 开发环境中 Docker 和 Vagrant 该如何选择? +答: +Docker 不是虚拟机,而是进程隔离,对于资源的消耗很少,但是目前需要 Linux 环境支持。Vagrant 是虚拟机上做的封装,虚拟机本身会消耗资源。 + +如果本地使用的 Linux 环境,推荐都使用 Docker。 + +如果本地使用的是 OSX 或者 Windows 环境,那就需要开虚拟机,单一开发环境下 Vagrant 更简单;多环境开发下推荐在 Vagrant 里面再使用 Docker 进行环境隔离。 + +## 其它 + +### Docker 能在非 Linux 平台(比如 Windows 或 MacOS)上运行么? +答:可以。目前需要使用 docker for mac、boot2docker 等软件创建一个轻量级的 Linux 虚拟机层。 + +### 如何将一台宿主主机的 docker 环境迁移到另外一台宿主主机 +答:停止 Docker 服务。将整个 Docker 存储文件夹复制到另外一台宿主主机,然后调整另外一台宿主主机的配置即可。 + +### 如何进入 Docker 容器的网络命名空间? +答:Docker 在创建容器后,删除了宿主主机上 `/var/run/netns` 目录中的相关的网络命名空间文件。因此,在宿主主机上是无法看到或访问容器的网络命名空间的。 + +用户可以通过如下方法来手动恢复它。 + +首先,使用下面的命令查看容器进程信息,比如这里的1234。 + +```sh +$ docker inspect --format='{{. State.Pid}} ' $container_id +1234 +``` +接下来,在 /proc 目录下,把对应的网络命名空间文件链接到 /var/run/netns 目录。 + +```sh +$ sudo ln -s /proc/1234/ns/net /var/run/netns/ +``` + +然后,在宿主主机上就可以看到容器的网络命名空间信息。例如 + +```sh +$ sudo ip netns show +1234 +``` + +此时,用户可以通过正常的系统命令来查看或操作容器的命名空间了。例如修改容器的 IP 地址信息为 `172.17.0.100/16`。 + +```sh +$ sudo ip netns exec 1234 ifconfig eth0 172.17.0.100/16 +``` diff --git
