Docker 安裝 Apache
方法一、docker pull httpd
查找 Docker Hub 上的 httpd 鏡像:
可以通過 Sort by 查看其他版本的 httpd，默認是最新版本 httpd:latest。
此外，我們還可以用 docker search httpd 命令來查看可用版本：
zaixian@zaixian:~/apache$ docker search httpd NAME DESCRIPTION STARS OFFICIAL AUTOMATED httpd The Apache HTTP Server .. 524 [OK] centos/httpd 7 [OK] rgielen/httpd-image-php5 Docker image for Apache... 1 [OK] microwebapps/httpd-frontend Httpd frontend allowing... 1 [OK] lolhens/httpd Apache httpd 2 Server 1 [OK] publici/httpd httpd:latest 0 [OK] publicisworldwide/httpd The Apache httpd webser... 0 [OK] rgielen/httpd-image-simple Docker image for simple... 0 [OK] solsson/httpd Derivatives of the offi... 0 [OK] rgielen/httpd-image-drush Apache HTTPD + Drupal S... 0 [OK] learninglayers/httpd 0 [OK] sohrabkhan/httpd Docker httpd + php5.6 (... 0 [OK] aintohvri/docker-httpd Apache HTTPD Docker ext... 0 [OK] alizarion/httpd httpd on centos with mo... 0 [OK] ...
這裏我們拉取官方的鏡像
zaixian@zaixian:~/apache$ docker pull httpd
等待下載完成後，我們就可以在本地鏡像列表裏查到REPOSITORY為httpd的鏡像。

方法二、通過 Dockerfile 構建
創建 Dockerfile
首先，創建目錄apache,用於存放後面的相關東西。
zaixian@zaixian:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf
www 目錄將映射為 apache 容器配置的應用程式目錄。
logs 目錄將映射為 apache 容器的日誌目錄。
conf 目錄裏的配置檔將映射為 apache 容器的配置檔。
進入創建的 apache 目錄，創建 Dockerfile。
FROM debian:jessie # add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added #RUN groupadd -r www-data && useradd -r --create-home -g www-data www-data ENV HTTPD_PREFIX /usr/local/apache2 ENV PATH $PATH:$HTTPD_PREFIX/bin RUN mkdir -p "$HTTPD_PREFIX" \ && chown www-data:www-data "$HTTPD_PREFIX" WORKDIR $HTTPD_PREFIX # install httpd runtime dependencies # https://httpd.apache.org/docs/2.4/install.html#requirements RUN apt-get update \ && apt-get install -y --no-install-recommends \ libapr1 \ libaprutil1 \ libaprutil1-ldap \ libapr1-dev \ libaprutil1-dev \ libpcre++0 \ libssl1.0.0 \ && rm -r /var/lib/apt/lists/* ENV HTTPD_VERSION 2.4.20 ENV HTTPD_BZ2_URL https://www.apache.org/dist/httpd/httpd-$HTTPD_VERSION.tar.bz2 RUN buildDeps=' \ ca-certificates \ curl \ bzip2 \ gcc \ libpcre++-dev \ libssl-dev \ make \ ' \ set -x \ && apt-get update \ && apt-get install -y --no-install-recommends $buildDeps \ && rm -r /var/lib/apt/lists/* \ \ && curl -fSL "$HTTPD_BZ2_URL" -o httpd.tar.bz2 \ && curl -fSL "$HTTPD_BZ2_URL.asc" -o httpd.tar.bz2.asc \ # see https://httpd.apache.org/download.cgi#verify && export GNUPGHOME="$(mktemp -d)" \ && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys A93D62ECC3C8EA12DB220EC934EA76E6791485A8 \ && gpg --batch --verify httpd.tar.bz2.asc httpd.tar.bz2 \ && rm -r "$GNUPGHOME" httpd.tar.bz2.asc \ \ && mkdir -p src \ && tar -xvf httpd.tar.bz2 -C src --strip-components=1 \ && rm httpd.tar.bz2 \ && cd src \ \ && ./configure \ --prefix="$HTTPD_PREFIX" \ --enable-mods-shared=reallyall \ && make -j"$(nproc)" \ && make install \ \ && cd .. \ && rm -r src \ \ && sed -ri \ -e 's!^(\s*CustomLog)\s+\S+!\1 /proc/self/fd/1!g' \ -e 's!^(\s*ErrorLog)\s+\S+!\1 /proc/self/fd/2!g' \ "$HTTPD_PREFIX/conf/httpd.conf" \ \ && apt-get purge -y --auto-remove $buildDeps COPY httpd-foreground /usr/local/bin/ EXPOSE 80 CMD ["httpd-foreground"]
Dockerfile檔中 COPY httpd-foreground /usr/local/bin/ 是將當前目錄下的httpd-foreground拷貝到鏡像裏，作為httpd服務的啟動腳本，所以我們要在本地創建一個腳本檔httpd-foreground
#!/bin/bash set -e # Apache gets grumpy about PID files pre-existing rm -f /usr/local/apache2/logs/httpd.pid exec httpd -DFOREGROUND
賦予 httpd-foreground 檔可執行許可權。
zaixian@zaixian:~/apache$ chmod +x httpd-foreground
通過 Dockerfile 創建一個鏡像，替換成你自己的名字。
zaixian@zaixian:~/apache$ docker build -t httpd .
創建完成後，我們可以在本地的鏡像列表裏查找到剛剛創建的鏡像。
zaixian@zaixian:~/apache$ docker images httpd REPOSITORY TAG IMAGE ID CREATED SIZE httpd latest da1536b4ef14 23 seconds ago 195.1 MB
使用 apache 鏡像
運行容器
docker run -p 80:80 -v $PWD/www/:/usr/local/apache2/htdocs/ -v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf -v $PWD/logs/:/usr/local/apache2/logs/ -d httpd
命令說明：
-p 80:80: 將容器的 80 端口映射到主機的 80 端口。
-v $PWD/www/:/usr/local/apache2/htdocs/: 將主機中當前目錄下的 www 目錄掛載到容器的 /usr/local/apache2/htdocs/。
-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf: 將主機中當前目錄下的 conf/httpd.conf 檔掛載到容器的 /usr/local/apache2/conf/httpd.conf。
-v $PWD/logs/:/usr/local/apache2/logs/: 將主機中當前目錄下的 logs 目錄掛載到容器的 /usr/local/apache2/logs/。
查看容器啟動情況：
zaixian@zaixian:~/apache$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 79a97f2aac37 httpd "httpd-foreground" ... 0.0.0.0:80->80/tcp sharp_swanson
