A docker container is a standard unit of software that packages up code and all its dependencies so that the application can run quickly from one computing environment to another.<\/p>\n\n\n\n

Host App\/Website On Docker Container<\/h2>\n\n\n\n

First, We have to create a Dockerfile for building an image for our website hosting.<\/strong><\/p>\n\n\n\n

FROM ubuntu:20.04\nENV TZ=Asia\/Kolkata\n\nMAINTAINER Sarthak-Dixit\n\nRUN apt-get update -y \\\n&& apt-get install tzdata \\\n&& apt-get install -y apache2 wget curl \\\n&& apt-get install -y unzip sed\\\n&& a2enmod rewrite \\\n&& export LANG=en_US.UTF-8 \\\n&& apt-get install -y software-properties-common \\\n&& apt-get install -y language-pack-en-base \\\n&& add-apt-repository ppa:ondrej\/php -y\\\n&& apt-get update -y \\\n&& apt-get install -y php8.1 php8.1-mysql php8.1-bcmath php8.1-gd php8.1-bz2 php8.1-xml php8.1-cli php8.1-common php8.1-intl php8.1-curl php8.1-zip php8.1-mbstring php8.1-soap libapache2-mod-php8.1 \\\n&& rm \/var\/www\/html\/* \\\n&& wget https:\/\/wordpress.org\/latest.zip \\\n&& unzip latest.zip \\\n&& mv wordpress\/* \/var\/www\/html \\\n&& cd \/var\/www\/html \\\n&& cp wp-config-sample.php wp-config.php \\\n&& sed -i -e 's\/database_name_here\/wordpress\/g' \/var\/www\/html\/wp-config.php \\\n&& sed -i -e 's\/username_here\/root\/g' \/var\/www\/html\/wp-config.php \\\n&& sed -i -e 's\/password_here\/qwerty\/g' \/var\/www\/html\/wp-config.php \\\n&& sed -i -e 's\/localhost\/mysql\/g' \/var\/www\/html\/wp-config.php\n\nEXPOSE 80\n\nRUN apt-get install -y supervisor \\\n&& mkdir -p \/var\/log\/supervisor\nenv APACHE_RUN_USER www-data\nenv APACHE_RUN_GROUP www-data\nenv APACHE_PID_FILE \/var\/run\/apache2.pid\nenv APACHE_RUN_DIR \/var\/run\/apache2\nenv APACHE_LOCK_DIR \/var\/lock\/apache2\nenv APACHE_LOG_DIR \/var\/log\/apache2\n\nCOPY supervisord.conf \/etc\/supervisor\/conf.d\/\n\nWORKDIR \/var\/www\/html\n\nCMD [\"\/usr\/bin\/supervisord\"]\n<\/code><\/pre>\n\n\n\n
Copy the code and save it as a file name of Dockerfile with your file editor.<\/p>\n\n\n\n
Secondly, create a supervisor configuration file. <\/p>\n\n\n\n
[supervisord]\nnodaemon=true\n\n[program:apache2]\ncommand=\/bin\/bash -c \"source \/etc\/apache2\/envvars && exec \/usr\/sbin\/apache2 -DFOREGROUND\"<\/code><\/pre>\n\n\n\n
Copy the code and save it as file-name of supervisord.conf with your file editor.<\/p>\n\n\n\n
Note: <\/strong>The file “supervisord.conf” is required to start the web-server service in the container and we can use this file to start other services as well.  <\/mark><\/p>\n\n\n\n
Now,<\/strong> We are building a docker image<\/a> by using the above-created Dockerfile.<\/p>\n\n\n\n
$ docker build -t wp-image <\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
The above command builds an image with the name wp-image. You can list all your docker images by using the command “docker images”.<\/p>\n\n\n\n
<\/p>\n\n\n\n
After building the image, We have to run the build image on the container.<\/strong><\/p>\n\n\n\n
Firstly, We run a MySQL container to store the database.<\/p>\n\n\n\n
\n
$ docker run -d --name mysql-cont -e MYSQL_ROOT_PASSWORD=qwerty -e MYSQL_DATABASE=wordpress mysql:5.7<\/code><\/pre>\n<\/blockquote>\n\n\n\n
<\/p>\n\n\n\n
And in the above command, We run the container with a detached terminal by “-d”, name of “mysql-cont” by using “–name”<\/p>\n\n\n\n
Create a database by using “ <\/mark>-e MYSQL_DATABASE=wordpress”<\/p>\n\n\n\n
Configure password in mysql root user by “-e MYSQL_ROOT_PASSWORD=” and using mysql:5.7 image in which “mysql” is the image name and “:5.7” is the version tag.<\/p>\n\n\n\n
Then, We run a container of our build image.<\/p>\n\n\n\n
\n
$ docker run -dit --name wordpress --link mysql-cont:mysql -p 8080:80 wp-image<\/code><\/pre>\n<\/blockquote>\n\n\n\n
In this command, Everything is the same as have we run the previous command of MySQL container except “–link”, “-it” and “-p”.<\/p>\n\n\n\n
Here, “-it” means instruct docker to give terminal interaction to the container.<\/p>\n\n\n\n
For creating links between containers, We use “–link” to link the WordPress container to the MySQL container for sharing resources of the database container.<\/p>\n\n\n\n
In porting while running a container we use  “-p” to attach the external port to the container’s port.<\/p>\n\n\n\n
8080 — refers base machine’s port.
80 — refers container’s port.<\/p>\n\n\n\n
After all the above processes, you will be able to browse the website at http:\/\/localhost:8080.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Dockerfile<\/span><\/strong><\/h2>\n\n\n\n
A docker file is a text file that includes all the commands a user can call on the command line to bring together an image<\/strong>.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Commands Use In Dockerfile Environment<\/span><\/strong><\/mark><\/h3>\n\n\n\n
FROM<\/mark> — <\/strong>Uses for fetching and using images from the base machine if present, otherwise, it will get it from the docker registry. <\/p>\n\n\n\n
RUN<\/mark> —<\/strong> For running commands in shell form over the image. <\/p>\n\n\n\n
CMD<\/mark> — <\/strong>Use to execute the command and It will be written in an executable set as [parameter-1, parameter-2].<\/p>\n\n\n\n
MAINTAINER<\/mark> — <\/strong>Use for maintaining Dockerfile author.<\/p>\n\n\n\n
EXPOSE<\/mark> — <\/strong>For exposing the port of the image.<\/p>\n\n\n\n
WORKDIR<\/mark>  — <\/strong>For setting the working directory of the image.<\/p>\n\n\n\n
ADD<\/mark> — <\/strong>Use for copying our local machine data to docker image as well as use URL to copy and extract tar directory from source to destination.<\/p>\n\n\n\n
COPY<\/mark> —<\/strong> For copying our local machine’s data to the docker image.<\/p>\n\n\n\n
env<\/mark> — <\/strong>For setting the environment in the docker image.<\/p>\n\n\n\n
IP Allocation To Container\/Assign Static IP To Docker Container<\/h2>\n\n\n\n
First, we have to create a network on docker.<\/p>\n\n\n\n
\n
$ docker network create --subnet=10.6.0.0\/16 mynetwork<\/code><\/pre>\n<\/blockquote>\n\n\n\n
And then, we run our container by using this network and assigning the static IP.<\/p>\n\n\n\n
\n
$ docker -d run --net mynetwork --ip 10.6.0.1 -p 8080:80 --name server wp-image<\/code><\/pre>\n<\/blockquote>\n\n\n\n
Communication between docker containers<\/h2>\n\n\n\n
A bridge network is an easy and default way to communicate between containers. Containers which is under the same bridge network will able to communicate by name or alias.<\/p>\n\n\n\n
\n
$ docker network ls<\/code><\/pre>\n<\/blockquote>\n\n\n\n
