一、使用docker run命令直接启动一个tomcat容器

1.1 下载官方tomcat镜像

[root@dev nginx]# docker search tomcat

1.3 浏览器查看

tomcat:8080

1.4 部署自己的web应用

将本地war包上传到宿主机/opt/tomcat8/目录下。
先停止原来的tomcat容器，然后重新挂在新的war包并启动。

[root@dev nginx]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES

[root@dev nginx]# docker rm 00a88a12a6f4

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES

[root@dev tomcat8]#

调用接口查看启动情况

tomcat：8080

容器正常启动。

二、使用docker file启动tomcat容器

2.1、编写docker file

在当前/opt/tomcat8/目录下创建dockerfile文件，写入如下内容：

from docker.io/tomcat:8.5.29    
MAINTAINER marvin(qdhaiqiang@163.com)   
COPY  webapps   /usr/local/tomcat/webapps
COPY  logs  /usr/local/tomcat/logs
COPY  conf/server.xml  /usr/local/tomcat/conf/server.xml

2. 2、用dockerfile 构建出镜tomcat镜像

[root@dev tomcat8]# docker build -t marvin/tomcat . 
Sending build context to Docker daemon 26.48 MB
Step 1/5 : FROM docker.io/tomcat:latest
 ---> 2d43521f2b1a

[root@dev tomcat8]#

查看新构建的镜像

[root@dev tomcat8]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

nginx_image1        latest              c4d5f5accc06        About an hour ago   109 MB
docker.io/tomcat    latest              2d43521f2b1a        5 days ago          463 MB
docker.io/nginx     latest              8b89e48b5f15        6 days ago          109 MB
[root@dev tomcat8]#

2.3、运行新构建的镜像

[root@dev tomcat8]# docker run --name tomcat8 -d -p 8080:8080  marvin/tomcat
6f189daf58807a5683a8b9d6c01b1b30ae8770045aa551535d27b641681c256a
[root@dev tomcat8]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
6f189daf5880        marvin/tomcat       "catalina.sh run"   3 seconds ago       Up 2 seconds        0.0.0.0:8080->8080/tcp   tomcat8
[root@dev tomcat8]#

2.4、查看镜像运行效果

tomcat.png

2.5、如果要配置https证书的话，可将jks的证书放于conf目录下，在server中使用相对路径引用证书，配置如下:

<Connector port="8888" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true" URIEncoding="UTF-8"  
               clientAuth="false" sslProtocol="TLS" keystoreFile="conf/SHA256withRSA__.haier.net.jks" keystorePass="20170905"/>

或者如果是pem文件的话

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxThreads="150" SSLEnabled="true" >
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="conf/localhost-rsa-key.pem"
                         certificateFile="conf/localhost-rsa-cert.pem"
                         certificateChainFile="conf/localhost-rsa-chain.pem"
                         type="RSA" />
        </SSLHostConfig>
</Connector>

2.6、在分布式微服务中的应用

tomcat作为web容器被广泛应用，但我们目前restful接口特别多，每个接口都需要一个tomcat来启动，为了配置隔离，一般都会把tomcat安装文件复制多遍，分别把war包部署在对应的webapp目录下，但这样造成的问题就是tomcat安装文件占用了大量的磁盘空间，且不便于统一管理。比如要修改tomcat的某个配置，那么对应的所有的tomcat目录都要修改一遍。

基于上述情况，作者设计了一种基于docker的tomcat服务化方案。

分布式应用

2.7、查看tomcat日志

因为tomcat日志是随着程序运行生成的，所以不能使用add或者copy宿主机目录的形式添加到容器，目前的思路是将容器中的logs整个目录copy到宿主机，实际应用中可用定时任务执行脚本的形式解决。

[root@dev logs]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
6f189daf5880        marvin/tomcat       "catalina.sh run"   4 hours ago         Up 4 hours          0.0.0.0:8080->8080/tcp   tomcat8
[root@dev logs]# 
[root@dev logs]# pwd
/opt/tomcat8/logs
[root@dev logs]# ll
total 0
[root@dev logs]#  docker cp 6f189daf5880:/usr/local/tomcat/logs /opt/tomcat8/
[root@dev logs]# ll

2.8 另一个tomcat+jdk的例子

#tomcat8 openjdk8

FROM centos:7

MAINTAINER fengzp <fengzp@gzyitop.com>

ENV LANG en_US.UTF-8
ENV TOMCAT_VERSION 8.5.13
ENV CATALINA_HOME /opt/apache-tomcat-$TOMCAT_VERSION
ENV PATH $CATALINA_HOME/bin:$PATH
ENV JDK_VERSION 1.8.0

WORKDIR $CATALINA_HOME

RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

RUN yum -y install java-$JDK_VERSION-openjdk-devel && rm -rf /var/cache/yum/*
ENV JAVA_HOME /usr/lib/jvm/java-openjdk

RUN yum -y install wget
RUN cd /opt/ && wget "http://apache.fayea.com/tomcat/tomcat-8/v$TOMCAT_VERSION/bin/apache-tomcat-$TOMCAT_VERSION.tar.gz"
RUN cd /opt/ && tar -zxf apache-tomcat-$TOMCAT_VERSION.tar.gz
RUN cd /opt/ && rm -rf apache-tomcat-$TOMCAT_VERSION.tar.gz
RUN chmod +x $CATALINA_HOME/bin/*.sh

VOLUME $CATALINA_HOME/webapps 
VOLUME $CATALINA_HOME/logs
VOLUME $CATALINA_HOME/conf

EXPOSE 8080

CMD $CATALINA_HOME/bin/startup.sh && tail -F $CATALINA_HOME/logs/catalina.out

三、不适用容器自带jdk

3.1 先将下载好的jdk和tomcat上传到宿主服务器

[root@dev tomcat8]# ls
apache-tomcat-7.0.70.tar.gz  jdk-7u80-linux-x64.tar.gz

3.2 dockerfile文件如下

#pull down centos image
FROM centos
MAINTAINER test@test.com
#copy jdk and tomcat into image
ADD ./apache-tomcat-7.0.70.tar.gz /root
ADD ./jdk-7u80-linux-x64.tar.gz /root
#set environment variable
ENV JAVA_HOME /root/jdk1.7.0_80
ENV PATH $JAVA_HOME/bin:$PATH
#define entry point which will be run first when the container starts up
ENTRYPOINT /root/apache-tomcat-7.0.70/bin/startup.sh && tail -F /root/apache-tomcat-7.0.70/logs/catalina.out

centos7 上用docker部署tomcat服务

>>>我的博客<<<

一、使用docker run命令直接启动一个tomcat容器

1.1 下载官方tomcat镜像

1.2 启动容器

1.3 浏览器查看

1.4 部署自己的web应用

二、使用docker file启动tomcat容器

2.1、编写docker file

2. 2、用dockerfile 构建出镜tomcat镜像

2.3、运行新构建的镜像

2.4、查看镜像运行效果

2.5、如果要配置https证书的话，可将jks的证书放于conf目录下，在server中使用相对路径引用证书，配置如下:

2.6、在分布式微服务中的应用

2.7、查看tomcat日志

2.8 另一个tomcat+jdk的例子

三、不适用容器自带jdk
