Dockers 101 – Series 9 of N – How to Setup Apache and NGINX Server Using Docker

Requirement:
- Setup Apache and NGinx server using docker
Strategy:
- First of all create source folders and html files for Apache and NGinx on the host drive so that it is used as mount/volume for the Apache and NGinx containers respectively
- Use docker run command with -v and -p options to specify the volume and port mapping
- Test the containers
Solution:
- If you have not installed docker on your system then first do that
  - #Use the below baseURL for your specific distro in the docker.repo file below
    CentOS6/RHEL6: https://yum.dockerproject.org/repo/main/centos/6
    CentOS7/RHEL7: https://yum.dockerproject.org/repo/main/centos/7
    Fedora20: https://yum.dockerproject.org/repo/main/fedora/20
    Fedora21: https://yum.dockerproject.org/repo/main/fedora/21
    Fedora22: https://yum.dockerproject.org/repo/main/fedora/22 cat >/etc/yum.repos.d/docker.repo <<-EOF
    [dockerrepo]
    name=Docker Repository
    baseurl=https://yum.dockerproject.org/repo/main/centos/7

    gpgcheck=1
    gpgkey=https://yum.dockerproject.org/gpg
    EOF yum -y update && yum -y install docker-engine sudo usermod -aG docker $USER
    cat /etc/group | grep docker sudo chown “$USER”:”$USER” /home/”$USER”/.docker -R
    sudo chmod g+rwx “/home/$USER/.docker” -R
- Create source folders and html files for Apache and NGinx on the host
  - rootPath=$(pwd)
    hostNginxPath=”$rootPath/docker/www/nginx”
    containerNginxPath=”/usr/share/nginx/html”
    hostNginxHtml=”$rootPath/docker/www/nginx/index.html”
    hostHttpdPath=”$rootPath/docker/www/httpd”
    hostHttpdHtml=”$rootPath/docker/www/httpd/index.html”
    containerHttpdPath=”/usr/local/apache2/htdocs” test -d $hostNginxPath && echo “$hostNginxPath exists, continuing…” || echo “$hostNginxPath does not exist, creating…” && mkdir -p $hostNginxPath
    echo ”

    <h1>This is a custom test page from My NGinx Server…</h1>

    cat $hostNginxHtml test -d $hostHttpdPath && echo “$hostHttpdPath exists, continuing…” || echo “$hostHttpdPath does not exist, creating…” && mkdir -p $hostHttpdPath
    echo ”

    <hr/>
    <h1>This is a custom test page from My Httpd Server…</h1>
    <hr/>
    </body>
    </html>
    ” > $hostHttpdHtml
    cat $hostHttpdHtml
- Use docker run command with -v and -p options
  - docker stop $(docker ps -a -q)
    docker rm $(docker ps -a -q)
    docker rmi $(docker images -q)
    docker run -d –name mynginxserver -p 8080:80 -v $hostNginxPath:$containerNginxPath nginx:latest
    docker exec mynginxserver cat $containerNginxPath/index.html
    docker run -d –name myhttpdserver -p 8090:80 -v $hostHttpdPath:$containerHttpdPath httpd:latest
    docker exec myhttpdserver cat $containerHttpdPath/index.html
- Test the containers
  - curl http://localhost:8080
    curl http://localhost:8090 docker images
    docker ps -a
