In your <code>Dockerfile</code>, add at the last line

<pre><code>ENTRYPOINT service ssh restart &amp;&amp; bash
</code></pre>

It works for me

And this is the result:

<pre><code>root@ubuntu:/home/vagrant/docker/add# docker run -i -t ubuntu
 * Restarting OpenBSD Secure Shell server sshd [ OK ] 
root@dccc354e422e:~# service ssh status
 * sshd is running
</code></pre>

blocks|key|4591341|text|还有另一种方法，我发现它更具可读性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4591342|假设你想要启动rabbitmq和mongodb，当你运行它的时候，你的CMD会是这样的：|offset|length|style|CODE|4591343|CMD+/etc/init.d/rabbitmq-server+start+&&+\

There's another way to do it that I've always found to be more readable.
Say that you want to start rabbitmq and mongodb when you run it then your <code>CMD</code> would look something like this:
<pre><code>CMD /etc/init.d/rabbitmq-server start &amp;&amp; \
 /etc/init.d/mongod start
</code></pre>
Since you can have only one <code>CMD</code> per <code>Dockerfile</code> the trick is to concatenate all instructions with <code>&amp;&amp;</code> and then use <code>\</code> for each command to start a new line.
If you end up adding to many of those I suggest you put all your commands in a script file and start it like <a href="https://stackoverflow.com/a/25150809/3621724">@larry-cai</a> suggested:
<pre><code>CMD /start.sh
</code></pre>

blocks|key|85079|text|在我的例子中，我有一个PHP+web应用程序，由Apache2在连接到MYSQL后端数据库的docker容器中提供服务。Larry+Cai的解决方案只做了一些细微的修改。我创建了一个entrypoint.sh文件，我在其中管理我的服务。我认为在容器启动时有多个命令要执行的情况下创建entrypoint.sh是引导docker的一种更简洁的方式。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|85080|#!/bin/sh

In my case, I have a PHP web application being served by Apache2 within the docker container that connects to a MYSQL backend database. Larry Cai's solution worked with minor modifications. I created a <code>entrypoint.sh</code> file within which I am managing my services. I think creating an <code>entrypoint.sh</code> when you have more than one command to execute when your container starts up is a cleaner way to bootstrap docker.

<pre><code>#!/bin/sh

set -e

echo "Starting the mysql daemon"
service mysql start

echo "navigating to volume /var/www"
cd /var/www
echo "Creating soft link"
ln -s /opt/mysite mysite

a2enmod headers
service apache2 restart

a2ensite mysite.conf
a2dissite 000-default.conf
service apache2 reload

if [ -z "$1" ]
then
 exec "/usr/sbin/apache2 -D -foreground"
else
 exec "$1"
fi
</code></pre>

This not works <code>CMD service mysql start &amp;&amp; /bin/bash</code> 

This not works <code>CMD service mysql start ; /bin/bash ;</code> 

-- i guess interactive mode would not support foreground. 

This works !! <code>CMD service nginx start ; while true ; do sleep 100; done;</code>

This works !! <code>CMD service nginx start &amp;&amp; tail -F /var/log/nginx/access.log</code>

beware you should using <code>docker run -p 80:80 nginx_bash</code> without command parameter.

<pre><code>docker export -o &lt;nameOfContainer&gt;.tar &lt;nameOfContainer&gt;
</code></pre>

Might need to prune the existing container using docker prune ... 

Import with required modifications:

<pre><code>cat &lt;nameOfContainer&gt;.tar | docker import -c "ENTRYPOINT service mysql start &amp;&amp; /bin/bash" - &lt;nameOfContainer&gt;
</code></pre>

Run the container for example with always restart option to make sure it will auto resume after host/daemon recycle:

<pre><code>docker run -d -t -i --restart always --name &lt;nameOfContainer&gt; &lt;nameOfContainer&gt; /bin/bash
</code></pre>

Side note:
In my opinion reasonable is to start only cron service leaving container as clean as possible then just modify crontab or cron.hourly, .daily etc... with corresponding checkup/monitoring scripts. Reason is You rely only on one daemon and in case of changes it is easier with ansible or puppet to redistribute cron scripts instead of track services that start at boot.
