Deploying Apache Web Server & Python On A Docker Container
This is a brief tutorial / walkthrough for:
- Deploying Apache Web Server on a Docker container
- Installing and Using Python on a Docker container
Deploying Apache Web Server on a Docker Container
Step 1: Pull CentOS 6 image from the Docker hub by typing docker pull centos:6
Step 2: Launch a container with CentOS 6 image by typing docker run -dit --name <your_container_name> centos:6
Step 3: Install Apache web server on the newly launched container by typing docker exec <your_container_name> yum install httpd -y
Step 4: Start the httpd service by typing docker exec <your_container_name> service httpd start
Step 5: Check if the web server is working by visiting the Local IP of the Docker container, which is 172.17.0.2 in this case. The page shown below is the default landing page provided by Apache.
Step 7: Create index.html file to customize the landing page on your own. This can be done by attaching the container to shell by typing docker attach <your_container_name> and creating a custom index.html file in the document root /var/www/html using vi / vim / your preferred CLI text editor.
Finally, we can test our website using the Local IP of the container, which appears as below in this case:
Installing and Using Python on a Docker container
Here, I'll be using the latest version of CentOS, i.e., CentOS 8.
Step 1: Launch a container using your desired container name and centos as the image. By not specifying the version, the latest version of the image will be downloaded from the Docker hub and will be used for our container.
Step 2: Install the python3 package by typing docker exec <your_container_name> yum install python3 -y
Step 3: Attach the container to the shell and create a custom .py file to test Python in the container. Once created, run the file by type python3 <file_name>.py in the container's bash prompt.
