1、 在安裝好php環境的容器，參考上面貼出的鏈接那篇文章的部分，做好基礎工作：
#創建工作目錄 mkdir /rootfs #進入工作目錄 cd /rootfs #創建基礎目錄 mkdir -p bin etc lib proc sys tmp dev/pts usr/lib64 usr/bin usr/local/bin #創建一個空的DNS服務用的文件 touch etc/resolv.conf #復制名稱解析文件 cp /etc/nsswitch.conf etc/nsswitch.conf #創建用戶和用戶組文件 echo root:x:0:0:root:/:/bin/sh > etc/passwd echo root:x:0: > etc/group #創建php程序運行的用戶 echo www:x:1001:1001:root:/:/bin/sh >> etc/passwd echo www:x:1001: >> etc/group #依賴庫軟鏈接 ln -s lib lib64 #工具軟鏈接 ln -s bin sbin #下載busybox，若網速慢可以用迅雷下載，然后復制到/sbin/busybox curl -o /sbin/busybox http://busybox.net/downloads/binaries/1.21.1/busybox-x86_64 #加權限 chmod +x /sbin/busybox #安裝busybox cp /sbin/busybox bin busybox --install -s bin
2、找依賴，假設我的php安裝在/usr/local/php中，用交互模式進入容器
運行命令查看依賴：
ldd /usr/local/php/sbin/php-fpm
ldd /usr/local/nginx/sbin/nginx
會列出一大堆依賴庫，並且這些庫在不同的路徑。由於用到busybox，那就將這些庫復制到工作目錄的根目錄的lib即可。即/rootfs/lib/中，用這個工具找出來的是不完整的、還有c++運行庫等等。
我整理出來的完整依賴庫是：
ldd /usr/local/sbin/php-fpm linux-vdso.so.1 (0x00007fff2cf62000) libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007fd1cc915000) libresolv.so.2 => /lib/x86_64-linux-gnu/libresolv.so.2 (0x00007fd1cc6fe000) libedit.so.2 => /usr/lib/x86_64-linux-gnu/libedit.so.2 (0x00007fd1cc4c5000) libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007fd1cc29b000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fd1cc093000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fd1cbe78000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fd1cbb77000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fd1cb973000) libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007fd1cb75b000) libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 (0x00007fd1cb3f4000) libssl.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007fd1cb193000) libcrypto.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007fd1cad96000) libcurl.so.4 => /usr/lib/x86_64-linux-gnu/libcurl.so.4 (0x00007fd1cab22000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd1ca777000) libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007fd1ca567000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fd1ca34a000) /lib64/ld-linux-x86-64.so.2 (0x00007fd1cd911000) liblzma.so.5 => /lib/x86_64-linux-gnu/liblzma.so.5 (0x00007fd1ca127000) libidn.so.11 => /usr/lib/x86_64-linux-gnu/libidn.so.11 (0x00007fd1c9ef3000) librtmp.so.1 => /usr/lib/x86_64-linux-gnu/librtmp.so.1 (0x00007fd1c9cd6000) libssh2.so.1 => /usr/lib/x86_64-linux-gnu/libssh2.so.1 (0x00007fd1c9aad000) libgssapi_krb5.so.2 => /usr/lib/x86_64-linux-gnu/libgssapi_krb5.so.2 (0x00007fd1c9862000) libkrb5.so.3 => /usr/lib/x86_64-linux-gnu/libkrb5.so.3 (0x00007fd1c958e000) libk5crypto.so.3 => /usr/lib/x86_64-linux-gnu/libk5crypto.so.3 (0x00007fd1c935d000) libcom_err.so.2 => /lib/x86_64-linux-gnu/libcom_err.so.2 (0x00007fd1c9159000) liblber-2.4.so.2 => /usr/lib/x86_64-linux-gnu/liblber-2.4.so.2 (0x00007fd1c8f4a000) libldap_r-2.4.so.2 => /usr/lib/x86_64-linux-gnu/libldap_r-2.4.so.2 (0x00007fd1c8cf8000) libgnutls-deb0.so.28 => /usr/lib/x86_64-linux-gnu/libgnutls-deb0.so.28 (0x00007fd1c89d9000) libhogweed.so.2 => /usr/lib/x86_64-linux-gnu/libhogweed.so.2 (0x00007fd1c87aa000) libnettle.so.4 => /usr/lib/x86_64-linux-gnu/libnettle.so.4 (0x00007fd1c8578000) libgmp.so.10 => /usr/lib/x86_64-linux-gnu/libgmp.so.10 (0x00007fd1c82f5000) libgcrypt.so.20 => /lib/x86_64-linux-gnu/libgcrypt.so.20 (0x00007fd1c8014000) libkrb5support.so.0 => /usr/lib/x86_64-linux-gnu/libkrb5support.so.0 (0x00007fd1c7e08000) libkeyutils.so.1 => /lib/x86_64-linux-gnu/libkeyutils.so.1 (0x00007fd1c7c04000) libsasl2.so.2 => /usr/lib/x86_64-linux-gnu/libsasl2.so.2 (0x00007fd1c79e8000) libp11-kit.so.0 => /usr/lib/x86_64-linux-gnu/libp11-kit.so.0 (0x00007fd1c77a2000) libtasn1.so.6 => /usr/lib/x86_64-linux-gnu/libtasn1.so.6 (0x00007fd1c758e000) libgpg-error.so.0 => /lib/x86_64-linux-gnu/libgpg-error.so.0 (0x00007fd1c737c000) libffi.so.6 => /usr/lib/x86_64-linux-gnu/libffi.so.6 (0x00007fd1c7173000)
ldd /usr/local/nginx/sbin/nginx linux-vdso.so.1 (0x00007fff3d5dd000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f7f01b3f000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7f01922000) libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f7f016eb000) libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f7f0147d000) libssl.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f7f0121c000) libcrypto.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007f7f00e1f000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f7f00c04000) libxml2.so.2 => /usr/lib/x86_64-linux-gnu/libxml2.so.2 (0x00007f7f0089d000) libxslt.so.1 => /usr/lib/x86_64-linux-gnu/libxslt.so.1 (0x00007f7f0065d000) libexslt.so.0 => /usr/lib/x86_64-linux-gnu/libexslt.so.0 (0x00007f7f00447000) libperl.so.5.20 => /usr/lib/x86_64-linux-gnu/libperl.so.5.20 (0x00007f7f00086000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f7effd85000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7eff9da000) /lib64/ld-linux-x86-64.so.2 (0x00007f7f01d43000) liblzma.so.5 => /lib/x86_64-linux-gnu/liblzma.so.5 (0x00007f7eff7b7000) libgcrypt.so.20 => /lib/x86_64-linux-gnu/libgcrypt.so.20 (0x00007f7eff4d6000) libgpg-error.so.0 => /lib/x86_64-linux-gnu/libgpg-error.so.0 (0x00007f7eff2c4000)
復制相應的.so包到rootfs目錄下
3、復制php程序
#復制PHP程序 cp -R /usr/local/php /rootfs/usr/local/php cp -R /usr/local/nginx /rootfs/usr/local/nginx
cp -R /usr/local/etc /rootfs/usr/local
4、打包tar文件
tar cf /rootfs.tar .
5、創建DockerFile
#將rootfs.tar 復制出來，其實這個已經是一個基於busybox+nginx+php創建的小型系統了 docker cp ngx01:/rootfs.tar .
FROM scratch ADD rootfs.tar / WORKDIR /usr/local/nginx/ptweb RUN apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32 \ && apt-get update \ && apt-get install supervisor -y \ && apt-get install cron -y \ && /bin/ln -svf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \ && echo 'Asia/Shanghai' >/etc/timezone \ && ln -svf /usr/local/nginx/sbin/nginx /usr/sbin/nginx \ && apt-get autoclean -y \ && apt-get clean -y \ && apt-get autoremove -y EXPOSE 80 ENTRYPOINT ["/usr/bin/supervisord", "-n", "-c", "/etc/supervisord.conf"]
然后build系統
docker build -t ngx-php-supervisor:v01 .
或者使用已經封裝過的rootfs.tar:https://github.com/lvelvis/docker-debian-artifacts/releases/download/v1.1/rootfs.tar.xz
