*How to design docker image *
docker run -itd ubuntu
docker exec -it “containerid” /bin/bash
install java
apt-get update
apt-get install openjdk-11-jdk -y
apt-get install openjdk-11-jdk-headless -y
install apache
apt-get install apache2 -y
Install wget
apt-get install wget -y
Install war file
wget https://tomcat.apache.org/tomcat-7.0-doc/appdev/sample/sample.war
chmod 755 sample.war
commit the image
docker commit -m"message" -a"satish" containerid name
docker images
Validate java and apache
docker exec containerid java
docker exec containerid which apache2
docker exec containerid ls /opt/
Saving and loading tar file
After committing the docker image
Save the file
docker save -o image.tar name of image
you can stop the containers if u want
Load the file
docker load -i image.tar
Pushing the docker image to repository
Create an account in docker hub
Login to docker hub in putty
docker login
provide username and password
tag the image matching to repo name
docker tag image sati1241/satishdevops
Push the image to repo
