Docker 安裝 Tomcat
阿新 • • 發佈：2018-12-26
方法一、通過 Dockerfile構建
建立Dockerfile
首先，建立目錄tomcat,用於存放後面的相關東西。
[email protected]:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
webapps目錄將對映為tomcat容器配置的應用程式目錄
logs目錄將對映為tomcat容器的日誌目錄
conf目錄裡的配置檔案將對映為tomcat容器的配置檔案
進入建立的tomcat目錄，建立Dockerfile

通過Dockerfile建立一個映象，替換成你自己的名字
[email protected]:~/tomcat$ docker build -t tomcat .
建立完成後，我們可以在本地的映象列表裡查詢到剛剛建立的映象
[email protected]:~/tomcat$ docker images|grep tomcat tomcat latest 70f819d3d2d97 days ago 335.8 MB
方法二、docker pull tomcat
查詢Docker Hub上的tomcat映象
[email protected]:~/tomcat$ docker search tomcat NAME DESCRIPTION STARS OFFICIAL AUTOMATED tomcat ApacheTomcatis an open source implementa...744[OK] dordoka/tomcat Ubuntu14.04,Oracle JDK 8andTomcat8 ba...19[OK] consol/tomcat-7.0Tomcat7.0.57,8080,"admin/admin"16[OK] consol/tomcat-8.0Tomcat8.0.15,8080,"admin/admin"14[OK] cloudesire/tomcat Tomcat server,6/7/88[OK] davidcaste/alpine-tomcat ApacheTomcat7/8usingOracleJava7/8 wi...6[OK] andreptb/tomcat DebianJessie based image withApacheTomc...4[OK] kieker/tomcat 2[OK] fbrx/tomcat MinimalTomcat image based on AlpineLinux2[OK] jtech/tomcat LatestTomcat production distribution on l...1[OK]
這裡我們拉取官方的映象
[email protected]:~/tomcat$ docker pull tomcat
等待下載完成後，我們就可以在本地映象列表裡查到REPOSITORY為tomcat的映象。（此處的tomcat給映象名稱，有很多比如：docker.io/tomcat等等）
使用tomcat映象
執行容器
[email protected]:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320 [email protected]:~/tomcat$
命令說明：
-p 8080:8080：將容器的8080埠對映到主機的8080埠
-v $PWD/test:/usr/local/tomcat/webapps/test：將主機中當前目錄下的test掛載到容器的/test
檢視容器啟動情況
[email protected]:~/tomcat$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES acb33fcb4beb tomcat "catalina.sh run"...0.0.0.0:8080->8080/tcp tomcat
