docker start a container after stopping

Question

I built a phalcon php image with this Dockerfile

FROM ubuntu:14.04

MAINTAINER betojulio

COPY apache2_evogas.conf /tmp/apache2.conf

RUN apt-get update && apt-get install -y \
    apache2 \
    php5-dev \
    php5-mysql \
    libapache2-mod-php5 \
    gcc \
    libpcre3-dev \
    git \
    && rm -rf /var/lib/apt/lists/* \
    && git clone git://github.com/phalcon/cphalcon.git \
    && cd cphalcon/build \
    && ./install \
    && cd /etc/php5/apache2/conf.d \
    && echo 'extension=phalcon.so' > phalcon_php.ini \
    && cp /tmp/apache2.conf /etc/apache2/apache2.conf \
    && a2enmod rewrite

CMD /usr/sbin/apache2ctl -D FOREGROUND

and I create the container running this command line

docker run -d -p 80:80 --name webserver -v /www:/var/www/html  betojulio/phalcon_project:1.0

and everything works well.

My question is, after I stop the container how do I restart the same container 'webserver' with the same options '-d -p 80:80 -v /www:/var/www/html' or after stopping the container I have to delete it and create it again?

Thank you in advance.

Answer 1

Like the other answer said, to start a stopped container, you run:

docker start <container name or id>

If it doesn't stay running, check the logs:

docker logs <container name or id>

If you want the container to restart automatically if it stops for some reason look at docker restart policies.

docker run -d --restart=unless-stopped -p 80:80 --name webserver -v /www:/var/www/html  betojulio/phalcon_project:1.0

Also, you might want to change your CMD to the following in your Dockerfile.

CMD ["apache2", "-D", "FOREGROUND"]

Answer 2

docker start webserver

That's it.
