###### The communication between the services well stablish? Does the communication use [smart EndPoints](https://medium.com/@nathankpeck/microservice-principles-smart-endpoints-and-dumb-pipes-5691d410700f)(ex: Request-Response, Observer)?
###### Does the code contain at least one DELETE query?
###### Is the use of the sqlite3 command missing from the code?
##### Try registering in the forum, open the database with `sqlite3 <database_name.db>` and perform a query to select all the users (Example: SELECT * FROM users;).
###### Does it present the user you created?
##### Try creating a post in the forum, open the database with `sqlite3 <database_name.db>` and perform a query to select all the users (Example: SELECT * FROM post;).
##### Try to run the command `"docker image build [OPTINS] PATH | URL | -"` to build the image using using the project Dockerfiles?
```
student$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
<nameoftheimage> latest 85a65d66ca39 7 seconds ago 795MB
```
###### Run the command `"docker images"` to see images. Does all images build as above?
##### Try running the command `"docker container run [OPTIONS] IMAGE [COMMAND] [ARG...]"` to start the containers using the images just created.
```
student$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cc8f5dcf760f ascii-art-web-docker "./server" 6 seconds ago Up 6 seconds 0.0.0.0:8080->8080/tcp ascii-art-web
```
###### Run the command `"docker ps -a"` to see containers. Is the docker containers running as above?
##### Try running the comment `"docker network ls"`
```
NETWORK ID NAME DRIVER SCOPE
24560f95a216 <network-name> bridge local
24560f95a216 bridge bridge local
3f12239adb4f host host local
159cdc8d8083 none null local
```
###### Is the network a bridge driver and does it appear in the list of networks as above?
##### Try openning a shell to the running container, using the [command](https://docs.docker.com/engine/reference/commandline/exec/) `"docker exec [OPTIONS] CONTAINER COMMAND [ARG...]"` (ex: `"docker exec -it <container-name> /bin/bash"`) and ping the other container that are connected to the same network, for [example](https://docs.docker.com/engine/tutorials/networkingcontainers/).
###### Did it ping with success? Are the multiple services/containers communicating between each other?
###### Does the project present no [unused object](https://docs.docker.com/config/pruning/)?
