 # Answers
 
-Lastname:
-Firstname:
+it was hard to realize this lab on docker playground, 
+it did'nt work well so I spent several days to fix it and finally had to install windows pro to use docker with my powershell
+
+Lastname: Bolland
+Firstname: Coline
 
 ## 2.2
-command:
+Start a docker container from the image you just created in the preceding question. 
+
+command: docker run coline
 
 ## 2.3
-question:
-command:
+question:Try to access to your service (with postman for example). 
+Restart container beeing careful to open needed port to get access to your service (see docker help).
+
+We need to open the port to get access as it's shown now on the screenshot of Postman example. 
+It could not work as it was not linked to any port.
+
+command: docker run -it -p 3000:3000 coline (dans powershell)
+EXPOSE 3000  (dans dockerfile)
 
 ## 2.5
 question:
-command:
 
-## 2.6
-command:
+Create yourself an account on Docker Hub
+Create a new repository attached to your account
+Then, push your image to your newly created repository
+
+Your image cannot be pushed as it is. Why ? Modify the name of your image and push it again on your new repository on Docker Hub. Write the command you use in answers.md file.
 
+command: docker login --username=colinebolland
+Docker Hub then asks for the password, that I entered to connect
+then I push the docker image to docker hub
+command: docker push colinebolland/devops-lab
+
+## 2.6
 question:
-command:
+Delete all your images created from the start of the lab on your computer.
+
+command: docker stop $(docker ps -a -q)
+	docker rm $(docker ps -a -q)
+	docker rmi -f $(docker images -a -q)
+
+(to cleanup docker images and containers
+stop all containers
+remove all containers
+remove all images)
+We have deleted all local images.
+command: docker images (on voit qu'il n'y a plus d'image cf. screenshot8)
+
+question: Start a container again with the name you pushed on Docker hub earlier. 
+command: docker run colineboland/devops-lab
+
+Here I have connected to my Docker Hub account and I pulled the image I just pushed. 
+Then it's able to find the image on which build the container.
+
+question: Start your container again in detached mode
+command: docker run --detach colinebolland/devops-lab
 
-command:
 
 ## 2.7
-question:
-question:
-command:
+question: Your container is normally started. In detached mode, how can you tell that container is started ? What is the name of your container ? 
+question:In detached mode we can tell if a container is starting by
+using the command to list containers: docker ps, show all running containers by default.
+we can see everything on the captures in the folder. 
+Restart your container by renaming it with a name corresponding to its function.
 
-command:
+command: docker ps
+command:docker run --name new --detach colinebolland/devops-lab
 
 ## 2.8
 question:
+docker exec new cat /etc/os-release
+
 output:
