+# Lab8
+
+## Task 1
+
+1. to list all the containers we could use `docker ps -a` (it is a shortcut I was looking for a long time) but `docker container ls -a` is also an appropriate command that does the same
+    ![alt text](1.png)
+
+2. I won't pull ubuntu since I already did resently (see [lab4](../lab4/submition4.md)). Also if it is a public image it could be pulled with `docker run <image>` in case it is not present in a system. However, it won't update witout pull
+
+3. Run ubuntu container with `docker run -it --name lab8 ubuntu`. In lab4 id did extra work by providing an `--entrypoint` to the container since initially I forgot about `it` flags. Nevertheless, results are the same
+    ![alt text](2.png)
+
+4. If attempt to remove image there would be an error since there are containers that uses this image. The containers could be removed with `docker rm <container_name/container_hash>`
+
+5. Also `docker rm` and `docker rmi` are a shortcuts for `docker container rm` and `docker image rm` respectively as well as `docker ps` is a shortcut for `docker container ls`
+
+## Task 2
+
+1. Create archive with ubntu iamge. The size is comparable

+
+2. Run nginx container with index
+    - `docker run -d -p 80:80 --name nginx_container nginx`
+    - `docker cp  ./submitions/lab8/index.html nginx_container:/usr/share/nginx/html/index.html`
+    - ![alt text](image.png)
+
+3. Commit container `docker commit nginx_container my_website:latest`
+4. Romove current container `docker stop nginx_container && docker rm nginx_container`
+5. Run commited container and test with curl
+    - `docker run -d -p 80:80 --name my_website_container my_website:latest`
+    - `curl`
+    ```
+    curl localhost

+
+6. `docker diff`
+
+    ![alt text](image-1.png)
+    - `docker diff` shows the changes in files from the initial image build. It could be seen on the original container
