简介： Docker 安装 Tomcat

Docker 教程之 Docker 安装 Tomcat 1

Docker 安装 Tomcat

方法一、docker pull tomcat
查找 Docker Hub 上的 Tomcat 镜像:

可以通过 Sort by 查看其他版本的 tomcat，默认是最新版本 tomcat:latest。

此外，我们还可以在控制台使用 docker search tomcat 命令来查看可用版本：

baidu@baidu:~/tomcat$ docker search tomcat

这里我们拉取官方的镜像：

baidu@baidu:~/tomcat$ docker pull tomcat
等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 tomcat 的镜像。

baidu@baidu:~/tomcat$ docker images|grep tomcat
tomcat latest 70f819d3d2d9 7 days ago 335.8 MB
方法二、通过 Dockerfile 构建
创建Dockerfile

首先，创建目录tomcat,用于存放后面的相关东西。

baidu@baidu:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
webapps 目录将映射为 tomcat 容器配置的应用程序目录。

logs 目录将映射为 tomcat 容器的日志目录。

conf 目录里的配置文件将映射为 tomcat 容器的配置文件。

进入创建的 tomcat 目录，创建 Dockerfile。

FROM openjdk:8-jre

ENV CATALINA_HOME /usr/local/tomcat
ENV PATH $CATALINA_HOME/bin:$PATH
RUN mkdir -p "$CATALINA_HOME"
WORKDIR $CATALINA_HOME

let "Tomcat Native" live somewhere isolated

ENV TOMCAT_NATIVE_LIBDIR $CATALINA_HOME/native-jni-lib
ENV LD_LIBRARY_PATH ${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}$TOMCAT_NATIVE_LIBDIR

runtime dependencies for Tomcat Native Libraries

Tomcat Native 1.2+ requires a newer version of OpenSSL than debian:jessie has available

> checking OpenSSL library version >= 1.0.2...

> configure: error: Your version of OpenSSL is not compatible with this version of tcnative

see http://tomcat.10.x6.nabble.com/VOTE-Release-Apache-Tomcat-8-0-32-tp5046007p5046024.html (and following discussion)

and https://github.com/docker-library/tomcat/pull/31

ENV OPENSSL_VERSION 1.1.0f-3+deb9u2
RUN set -ex; \
currentVersion="$(dpkg-query --show --showformat '${Version}\n' openssl)"; \
if dpkg --compare-versions "$currentVersion" '<<' "$OPENSSL_VERSION"; then \
if ! grep -q stretch /etc/apt/sources.list; then \

only add stretch if we're not already building from within stretch

        { \
            echo 'deb http://deb.debian.org/debian stretch main'; \
            echo 'deb http://security.debian.org stretch/updates main'; \
            echo 'deb http://deb.debian.org/debian stretch-updates main'; \
        } > /etc/apt/sources.list.d/stretch.list; \
        { \

add a negative "Pin-Priority" so that we never ever get packages from stretch unless we explicitly request them

            echo 'Package: *'; \
            echo 'Pin: release n=stretch*'; \
            echo 'Pin-Priority: -10'; \
            echo; \

... except OpenSSL, which is the reason we're here

            echo 'Package: openssl libssl*'; \
            echo "Pin: version $OPENSSL_VERSION"; \
            echo 'Pin-Priority: 990'; \
        } > /etc/apt/preferences.d/stretch-openssl; \
    fi; \
    apt-get update; \
    apt-get install -y --no-install-recommends openssl="$OPENSSL_VERSION"; \
    rm -rf /var/lib/apt/lists/*; \
fi

RUN apt-get update && apt-get install -y --no-install-recommends \

sh removes env vars it doesn't support (ones with periods)

find ./bin/ -name '*.sh' -exec sed -ri 's|^#!/bin/sh$|#!/usr/bin/env bash|' '{}' +

verify Tomcat Native is working properly

EXPOSE 8080
CMD ["catalina.sh", "run"]
通过 Dockerfile 创建一个镜像，替换成你自己的名字：

baidu@baidu:~/tomcat$ docker build -t tomcat .
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：

baidu@baidu:~/tomcat$ docker images|grep tomcat
