To Build Docker image using Docker files on Fedora 34

Introduction:

Docker images are unchangeable files that contain source code, libraries, dependencies, tools, and other files that are needed to run an application.

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

[root@linuxhelp ~]# cat /etc/os-release
NAME=Fedora
VERSION="34 (Workstation Edition)"
ID=fedora
VERSION_ID=34
VERSION_CODENAME=""
PLATFORM_ID="platform:f34"
PRETTY_NAME="Fedora 34 (Workstation Edition)"
ANSI_COLOR="0;38;2;60;110;180"
LOGO=fedora-logo-icon
CPE_NAME="cpe:/o:fedoraproject:fedora:34"
BUG_REPORT_URL="https://bugzilla.redhat.com/"
REDHAT_BUGZILLA_PRODUCT="Fedora"
REDHAT_BUGZILLA_PRODUCT_VERSION=34
REDHAT_SUPPORT_PRODUCT="Fedora"
REDHAT_SUPPORT_PRODUCT_VERSION=34
PRIVACY_POLICY_URL="https://fedoraproject.org/wiki/Legal:PrivacyPolicy"
VARIANT="Workstation Edition"
VARIANT_ID=workstation

Step 2: To check the docker installed status by using the below command

[root@linuxhelp ~]# dnf list --installed | grep docker
containerd.io.x86_64                              1.4.12-3.1.fc34                      @docker-ce-stable 
docker-ce.x86_64                                  3:20.10.12-3.fc34                    @docker-ce-stable 
docker-ce-cli.x86_64                              1:20.10.12-3.fc34                    @docker-ce-stable 
docker-ce-rootless-extras.x86_64                  20.10.12-3.fc34                      @docker-ce-stable 
docker-scan-plugin.x86_64                         0.12.0-3.fc34                        @docker-ce-stable 

Step 3: To create directory for the docker file by using the below command

 [root@linuxhelp ~]# mkdir dockerfiles

Step 4: To open the configuration file by using the below command

 [root@linuxhelp ~]# vim dockerfiles/dockerfile
# Getting image from docker hub
FROM httpd

RUN apt-get update

CMD ["echo","Apache web server image"]

Step 5: To run the docker build using the below command

 [root@linuxhelp ~]# docker build dockerfiles/

Step 7: To check the docker image running status by using the below command

 [root@linuxhelp ~]# docker run 4c078ce14461
