To Mount Host System's Volume to the Docker Container on Rocky Linux 8.6

Introduction:

Docker is a platform for fast building, testing, and deploying applications. In Docker, the software is packaged into standardized units called containers. Containers contain the libraries, tools, code, and runtime that the software needs to run.

Installation Procedure:

Step 1: Check the OS version by using the below command

[root@linuxhelp ~]# cat /etc/os-release 
NAME="Rocky Linux"
VERSION="8.6 (Green Obsidian)"
ID="rocky"
ID_LIKE="rhel centos fedora"
VERSION_ID="8.6"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Rocky Linux 8.6 (Green Obsidian)"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:rocky:rocky:8:GA"
HOME_URL="https://rockylinux.org/"
BUG_REPORT_URL="https://bugs.rockylinux.org/"
ROCKY_SUPPORT_PRODUCT="Rocky Linux"
ROCKY_SUPPORT_PRODUCT_VERSION="8"
REDHAT_SUPPORT_PRODUCT="Rocky Linux"
REDHAT_SUPPORT_PRODUCT_VERSION="8"

Step 2: Check the status of Docker by using the below command

[root@linuxhelp ~]# systemctl status docker.service 
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)

Step 3: Pull the caddy Web Server Container from the Docker Hub by using the below command

[root@linuxhelp ~]# docker pull caddy
Using default tag: latest
latest: Pulling from library/caddy
530afca65e2e: Pull complete 
4ba0a25d6623: Pull complete 
7a501877fabb: Pull complete 
d2c62335257e: Pull complete

Digest: sha256:f51603577fef8abe01dfda4b5ef85b3acf2844a6b3d0db873f5119f57db5de57
Status: Downloaded newer image for caddy:latest
docker.io/library/caddy:latest

Step 4: Create a Directory as caddy by using the below command

[root@linuxhelp ~]# mkdir caddy

Step 5: Change to the caddy directory by using the below command

root@linuxhelp ~]# cd caddy/

Step 6: Create a .html file for content in Web Server by using the below command

[root@linuxhelp caddy]# echo "welcome to linuxhelp" > index.html

Step 7: Create a Data directory for Mounting to the Container by using the below command

[root@linuxhelp caddy]# mkdir caddy_data

Step 8: Run the Caddy Container in port 80 with Mounting the Create Directories from Host System by using the below command

[root@linuxhelp caddy]# docker run -d -p 80:80 \
> -v $PWD/index.html:/usr/share/caddy/index.html \
> -v $PWD/caddy_data:/data \
> caddy
