Docker 安裝 tomcathtml

方法1、docker pull tomcat
查找Docker Hub上的tomcat鏡像

runoob@runoob:~/tomcat$ docker pull tomcat
等待下載完成後，咱們就能夠在本地鏡像列表裏查到REPOSITORY爲tomcat的鏡像。

方法2、經過 Dockerfile 構建
建立Dockerfile
首先，建立目錄tomcat,用於存放後面的相關東西。

runoob@runoob:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
webapps目錄將映射爲tomcat容器配置的應用程序目錄
logs目錄將映射爲tomcat容器的日誌目錄
conf目錄裏的配置文件將映射爲tomcat容器的配置文件
進入建立的tomcat目錄，建立Dockerfile

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.co... (and following discussion)

and https://github.com/docker-lib...

ENV OPENSSL_VERSION 1.1.0f-3+deb9u2
RUN set -ex; \shell

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; \
