方法一、docker pull nginx(推荐)

查找 Docker Hub 上的 nginx 镜像

root@mojotv:~/nginx$ docker search nginx
NAME                      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

这里我们拉取官方的镜像

root@mojotv:~/nginx$ docker pull nginx

等待下载完成后,我们就可以在本地镜像列表里查到 REPOSITORY 为 nginx 的镜像.

root@mojotv:~/nginx$ docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest 555bbd91e13c  3 days ago 182.8 MB

方法二、通过 dockerfile 构建(不推荐)

创建 dockerfile

首先,创建目录 nginx, 用于存放后面的相关东西.

root@mojotv:~$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf

www: 目录将映射为 nginx 容器配置的虚拟目录.

logs: 目录将映射为 nginx 容器的日志目录.

conf: 目录里的配置文件将映射为 nginx 容器的配置文件.

进入创建的 nginx 目录,创建 dockerfile 文件,内容如下:

FROM debian:stretch-slim

LABEL maintainer="NGINX Docker Maintainers <docker-maint@nginx.com>" ENV NGINX_VERSION 1.14.0-1~stretch
ENV NJS_VERSION 1.14.0.0.2.0-1~stretch

RUN set  -x \
    && apt-get update \&& apt-get install --no-install-recommends --no-install-suggests -y gnupg1 apt-transport-https ca-certificates \
    && \
    NGINX_GPGKEY=573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62; \
    found=''; \for server in \

        hkp://keyserver.ubuntu.com:80 \ hkp://p80.pool.sks-keyservers.net:80 \ pgp.mit.edu \
    ;  do \
        echo "Fetching GPG key $NGINX_GPGKEY from $server"; \
        apt-key adv --keyserver "$server"  --keyserver-options timeout=10  --recv-keys "$NGINX_GPGKEY"  && found=yes &&  break; \done; \
    test -z "$found"  && echo >&2  "error: failed to fetch GPG key $NGINX_GPGKEY"  &&  exit  1; \
    apt-get remove --purge --auto-remove -y gnupg1 && rm -rf /var/lib/apt/lists/* \

    && case "$dpkgArch" in \
        amd64|i386) \
# arches officialy built by upstream
            echo "deb https://nginx.org/packages/debian/ stretch nginx" >> /etc/apt/sources.list.d/nginx.list \
            && apt-get update \
            ;; \
        *) \
# we're on an architecture upstream doesn't officially build for
# let's build binaries from the published source packages
            echo "deb-src https://nginx.org/packages/debian/ stretch nginx" >> /etc/apt/sources.list.d/nginx.list \
            \
# new directory for storing sources and .deb files
            && tempDir="$(mktemp -d)" \
            && chmod 777 "$tempDir" \
# (777 to ensure APT's "_apt" user can access it too)
            \
# save list of currently-installed packages so build dependencies can be cleanly removed later
            && savedAptMark="$(apt-mark showmanual)" \
            \
# build .deb files from upstream's source packages (which are verified by apt-get)
            && apt-get update \
            && apt-get build-dep -y $nginxPackages \
            && ( \
                cd "$tempDir" \
                && DEB_BUILD_OPTIONS="nocheck parallel=$(nproc)" \
                    apt-get source --compile $nginxPackages \
            ) \
# we don't remove APT lists here because they get re-downloaded and removed later
            \
# reset apt-mark's "manual" list so that "purge --auto-remove" will remove all build dependencies
# (which is done after we install the built packages so we don't have to redownload any overlapping dependencies)
            && apt-mark showmanual | xargs apt-mark auto > /dev/null \
            && { [ -z "$savedAptMark" ] || apt-mark manual $savedAptMark; } \
            \
# create a temporary local APT repo to install from (so that dependency resolution can be handled by APT, as it should be)
            && ls -lAFh "$tempDir" \
            && ( cd "$tempDir" && dpkg-scanpackages . > Packages ) \
            && grep '^Package: ' "$tempDir/Packages" \
            && echo "deb [ trusted=yes ] file://$tempDir ./" > /etc/apt/sources.list.d/temp.list \
# work around the following APT issue by using "Acquire::GzipIndexes=false" (overriding "/etc/apt/apt.conf.d/docker-gzip-indexes")
#   Could not open file /var/lib/apt/lists/partial/_tmp_tmp.ODWljpQfkE_._Packages - open (13: Permission denied)
#   ...
#   E: Failed to fetch store:/var/lib/apt/lists/partial/_tmp_tmp.ODWljpQfkE_._Packages  Could not open file /var/lib/apt/lists/partial/_tmp_tmp.ODWljpQfkE_._Packages - open (13: Permission denied)
            && apt-get -o Acquire::GzipIndexes=false update \
            ;; \
    esac \
    \
    && apt-get install --no-install-recommends --no-install-suggests -y \
                        $nginxPackages \
                        gettext-base \
    && apt-get remove --purge --auto-remove -y apt-transport-https ca-certificates && rm -rf /var/lib/apt/lists/* /etc/apt/sources.list.d/nginx.list \
    \
# if we have leftovers from building, let's purge them (including extra, unnecessary build deps)
    && if [ -n "$tempDir" ]; then \
        apt-get purge -y --auto-remove \
        && rm -rf "$tempDir" /etc/apt/sources.list.d/temp.list; \
    fi

# forward request and error logs to docker log collector
RUN ln -sf /dev/stdout /var/log/nginx/access.log \
    && ln -sf /dev/stderr /var/log/nginx/error.log

EXPOSE 80

STOPSIGNAL SIGTERM

CMD ["nginx", "-g", "daemon off;"]

通过 dockerfile 创建一个镜像,替换成您自己的名字.

docker build -t nginx .

创建完成后,我们可以在本地的镜像列表里查找到刚刚创建的镜像

root@mojotv:~/nginx$ docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest 555bbd91e13c  3 days ago 182.8 MB

使用 nginx 镜像

运行容器

root@mojotv:~/nginx$ docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs -d nginx 45c89fab0bf9ad643bc7ab571f3ccd65379b844498f54a7c8a4e7ca1dc3a2c1e root@mojotv:~/nginx$

命令说明:

  • -p 80:80:将容器的80端口映射到主机的80端口
  • –name mynginx:将容器命名为mynginx
  • -v $PWD/www:/www:将主机中当前目录下的www挂载到容器的/www
  • -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf:将主机中当前目录下的nginx.conf挂载到容器的/etc/nginx/nginx.conf
  • -v $PWD/logs:/wwwlogs:将主机中当前目录下的logs挂载到容器的/wwwlogs

查看容器启动情况

root@mojotv:~/nginx$ docker ps
CONTAINER ID        IMAGE        COMMAND                      PORTS                         NAMES 45c89fab0bf9 nginx "nginx -g 'daemon off"  ...  0.0.0.0:80->80/tcp,  443/tcp   mynginx
f2fa96138d71        tomcat "catalina.sh run"  ...  0.0.0.0:81->8080/tcp          tomcat
