dockerfile说明FROM： 基础镜像。一切从这里开始构建 centos
MAINTAINER： 镜像是谁写的。姓名 + 邮箱
RUN： docker构建时需要执行的命令
ADD： 复制指令，从上下文目录中复制文件或者目录到容器里指定路径。
- ADD 的优点： 在执行 <源文件> 为 tar 压缩文件的话，压缩格式为 gzip, bzip2 以及 xz 的情况下，会自动复制并解压到 <目标路径>。
- ADD 的缺点： 在不解压的前提下，无法复制 tar 压缩文件。会令镜像构建缓存失效，从而可能会令镜像构建变得比较缓慢。具体是否使用，可以根据是否需要自动解压来决定。
WORKDIR： 指定工作目录。用 WORKDIR 指定的工作目录，会在构建镜像的每一层中都存在。（WORKDIR 指定的工作目录，必须是提前创建好的）。
docker build 构建镜像过程中的，每一个 RUN 命令都是新建的一层。只有通过 WORKDIR 创建的目录才会一直存在。
VOLUME： 定义匿名数据卷。在启动容器时忘记挂载数据卷，会自动挂载到匿名卷。
作用：
- 避免重要的数据，因容器重启而丢失，这是非常致命的。
- 避免容器不断变大。
EXPOSE： 仅仅只是声明端口。
作用：
- 帮助镜像使用者理解这个镜像服务的守护端口，以方便配置映射。
- 在运行时使用随机端口映射时，也就是 docker run --privileged=true -P 时，会自动随机映射 EXPOSE 的端口。
CMD： 指定这个容器启动的时候运行的命令
- CMD 在docker run --privileged=true 时运行。
- RUN 是在 docker build。
- 只有最后一个剩下可被代替
ENTRYPOINT： 指定这个容器启动的时候运行的命令
- 如果运行 docker run --privileged=true 时使用了 --entrypoint 选项，将覆盖 CMD 指令指定的程序。
- 优点：在执行 docker run --privileged=true 的时候可以指定 ENTRYPOINT 运行所需的参数。
- 注意：如果 Dockerfile 中如果存在多个 ENTRYPOINT 指令，仅最后一个生效。
ONBUILD： 用于延迟构建命令的执行。
假设镜像为 test-build，当有新的 Dockerfile 使用了之前构建的镜像 FROM test-build ，这时执行新镜像的 Dockerfile 构建时候，会执行 test-build 的 Dockerfile 里的 ONBUILD 指定的命令。
COPY： 复制指令，从上下文目录中复制文件或者目录到容器里指定路径。
COPY [--chown=<user>:<group>] <源路径1>... <目标路径>
COPY [--chown=<user>:<group>] ["<源路径1>",... "<目标路径>"]说明：
- [--chown=:]：可选参数，用户改变复制到容器内文件的拥有者和属组。
- <源路径>：源文件或者源目录，这里可以是通配符表达式，其通配符规则要满足 Go 的 filepath.Match 规则。例如：
- <目标路径>：容器内的指定路径，该路径不用事先建好，路径不存在的话，会自动创建。
ENV： 构建的时候设置环境变量
如设置 NODE_VERSION 7.2.0 ， 在后续的指令中可以通过 $NODE_VERSION 引用
构建自己的docker镜像

docker网络类型
- bridge：docker默认的网络驱动。 如果未指定驱动程序，则这是需要创建的网络类型。 当应用程序在需要通信的独立容器中运行时，通常会使用桥接网络。
当多个容器在同一个Docker主机上进行通信时，用户定义的桥接网络是最佳选择。
- host：对于独立的容器，删除容器和Docker主机之间的网络隔离，并直接使用主机的网络（若启用特权容器，将可以直接修改宿主机网络设置）。 host仅适用于Docker 17.06及更高版本上的swarm群集服务。
当网络堆栈不应与Docker主机隔离时，主机网络最佳，但您希望隔离容器的其他方面。
- overlay：Overlay networks将多个Docker守护程序连接在一起，并使swarm群集服务能够相互通信 。 还可以使用Overlay networks来促进swarm群集服务和独立容器之间的通信，或者在不同Docker守护程序上的两个独立容器之间进行通信。 此策略无需在这些容器之间执行OS级别的路由。
不同Docker主机上运行的容器进行通信时，或当多个应用程序使用swarm服务协同工作时，覆盖网络overlay是最佳选择。
- macvlan：Macvlan网络允许为容器分配MAC地址，使其显示为网络上的物理设备。 Docker守护程序通过其MAC地址将流量路由到容器。 macvlan在处理期望直接连接到物理网络的传统应用程序时，使用该驱动程序有时是最佳选择，而不是通过Docker主机的网络堆栈进行路由。
当您从VM设置迁移或需要您的容器看起来像网络上的物理主机（每个都具有唯一的MAC地址）时，Macvlan网络是最佳的。
- none：对于此容器，禁用所有网络。 通常与自定义网络驱动程序一起使用，none不适用于swarm集群服务。

[root@localhost patch]# docker load < centos8.tar.gz- 查看容器使用的IP
docker inspect --format='{{.NetworkSettings.Networks.deyatech.IPAddress}}' nginx
- 修改 ip 和 port
cd /var/lib/docker/containers/容器ID/
vim hostconfig.json
修改HostIp和HostPort，若绑定0.0.0.0，则HostIp改为空就行。例：{"HostIp":"","HostPort":"9200"}
