方法一、docker pull tomcat

查找 Docker Hub 上的 Tomcat 镜像:

The latest MySQL 8.0 version is available to install from the default AppStream repository using the MySQL module that is enabled by default on the CentOS 8 and RHEL 8 systems. There is also MariaDB 10.3 database version is available to install from the default AppStream repository, which is “ drop-in replacement ” for MySQL 5.7, with some. Debian is a Linux distribution that's composed entirely of free and open-source software. Improve this doc Balena base images. Balenalib is the central home for 26000+ IoT focused Docker images built specifically for balenaCloud and balenaOS.This set of images provide a way to get up and running quickly and easily, while still providing the option to deploy slim secure images to the edge when you go to production. This tutorial provides a starting point on how to install Docker, create and run Docker containers on CentOS/RHEL 8/7, but barely scratches the surface of Docker. Step 1: Install and Configure Docker. Earlier versions of Docker were called docker or docker-engine, if you have these installed, you must uninstall them before installing a newer. In this section, we will show you how to use Docker on your Raspberry Pi 4. If you have never used Docker, this section should help you get started. To run a Docker container, you need a Docker image on which the Docker container will be based. There are thousands of Docker containers available in the Docker container registry (Docker Hub).

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，我们还可以用 docker search tomcat 命令来查看可用版本：

这里我们拉取官方的镜像：

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。

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。

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。

通过 Dockerfile 创建一个镜像，替换成你自己的名字：

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：

使用 tomcat 镜像

运行容器

命令说明：

Docker Install Debian 8.1

-p 8080:8080：将主机的 8080 端口映射到容器的 8080 端口。

-v $PWD/test:/usr/local/tomcat/webapps/test：将主机中当前目录下的 test 挂载到容器的 /test。

查看容器启动情况
