Docker creates an image with Tomcat installed

Docker creates an image with Tomcat installed with the process: Download the image first, start the container with mirroring, install Tomcat in the container, and then save the Tomcat container as a new image.

There are many ways Docker downloads images, such as

sudo docker pull ubuntu:14.04

14.04 means the image label of Ubuntu, if not tagged, Docker will automatically download the image of the latest tag.

Start a container with a mirror by the Run command

or use

To specify the name of the container when the container starts.

You can then install Tomcat in the container.

Specific installation method, I am here to provide a more complete download from the image to the Tomcat installation of an article

Here is a little note that the image used in the article is not ubuntu:14.04, such as the use of ubuntu:14.04 may have a problem:

1, after installing SSH and using SSH login (~$ ssh root@127.0.0.1-p 49154), there will be Permission denied please try again.

There are a number of solutions available online for this error. The specific three categories are as follows:

A. Modify the/etc/ssh/sshd-config file to modify the Permitrootlogin No to yes,pubkeyauthentication Yes to no,authorizedkeysfile. ssh/ Authorized_keys Front plus # shield off, passwordauthentication no change to Yes

B. Modify the/etc/ssh/sshd-config file to modify the Permitrootlogin, pubkeyauthentication and passwordauthentication to Yes

C, modify the/etc/ssh/sshd-config file, change the Permitrootlogin and passwordauthentication to Yes

I read my own this file, because pubkeyauthentication is yes so I will permitrootlogin, passwordauthentication modified to Yes can be landed, in particular, according to the circumstances of their own choice.

2, in the installation

Apt-get Install python-software-properties
add-apt-repository Ppa:webupd8team/java

The solutions available online are:
