2-Tier Application Deployment with Docker in One Video | Episode 2

Thanks for the knowledge sharing. I have 2 questions :
How to log in to the container when it is created using docker-compose?
how do pass the container name in docker-compose?

Can we go with the docker compose directly instead of creating that image first and containers for both separately???

We mentioned flaskapp image name which is getting pull from docker hub in docker-compose.yml under the services so ít necessary to have that image first ??? Because then u will have to create the image first separately to push on docker hub. Why we will follow both things when we can do this by docker compose directly

learn with fun, i like this channel💯

I don't mind even if it's too long. it did help me a lot. thanks

Thanks shubham docker ke sb concepts clear ho gye
Great explaination

I'm a beginner, but your way of explaining really helps clarify all the concepts for me, Bhaiya. Thank you!

Shubam sir outstanding ha. Ap ne mery concept clear kr diye Thanks Bro.. ❤❤😊

very nice video sir. please share the commands for Docker.

Hi bhaiya! you explained it really well, but i am stuck at the point which shows error - OperationalError
MySQLdb.OperationalError: (1044, "Access denied for user 'admin'@'%' to database 'myDb'") , what to do?

Now, for your better learning, I'll give you a small task that will enhance your learning even more. You need to remove 'Hello Dosto'... from the HTML file, and for this, you'll need to make changes in the HTML file.... Question: Do you need to rebuild the image? or Just recreate the container? Doing this will provide great learning... And lastly, Thank you so much, Shubham Sir, for this amazing series. Also, it's beginner-friendly; anyone can start with it.

you're the best

thank God i came across this..

thanks shubham for this video. :) request you to please make a detailed video on deployment of 3 tier application(end to end project) using jenkins,terraform,kubernetes,docker, vpc. i.e please try to include all the tool in a project so that we understand how everything works in a realtime prod environment. would really appreciate if you can please make a video.

Bhaiya eco ho gya video

thank you sir for this

nice explanation

why does the container exit as soon as it is run and how to fix this ?

If anybody is facing issue with flaskapp container getting existed within a second or minute try following step with lot of debugging i tried this
It looks like the MySQL user `admin` doesn't have the necessary permissions to create a database. This is why you're seeing an `Access denied` error.

To resolve this, you need to grant the necessary permissions to the `admin` user. Here’s how you can do it:

1. **Access the MySQL Container with Root Privileges**:

Since you can't create a database with the `admin` user, you'll need to use the root user to grant the necessary permissions. First, access the MySQL container with the root user:

```bash
docker exec -it mysql mysql -u root -p
```

Enter the root password when prompted. If you didn't set a root password, the default is often empty.

2. **Grant Permissions to the `admin` User**:

Once you're in the MySQL shell as the root user, execute the following commands to grant permissions to the `admin` user:

```sql
GRANT ALL PRIVILEGES ON . TO 'admin'@'%' IDENTIFIED BY 'admin' WITH GRANT OPTION;
FLUSH PRIVILEGES;
```

This grants the `admin` user full privileges on all databases. You can modify the privileges to be more restrictive if needed.

3. **Create the Database**:

After granting the permissions, try creating the database again:

```bash
docker exec -it mysql mysql -u admin -padmin -e "CREATE DATABASE IF NOT EXISTS myDb;"
```

4. **Verify the Database Creation**:

Check if the database has been created:

```bash
docker exec -it mysql mysql -u admin -padmin -e "SHOW DATABASES;"
```

5. **Restart Your Flask Container**:

If the database now exists and is accessible, restart your Flask container:

```bash
docker run -d -p 5000:5000 --network=twotier -e MYSQL_HOST=mysql -e MYSQL_USER=admin -e MYSQL_PASSWORD=admin -e MYSQL_DB=myDb --name=flaskapp flaskapp:latest
```

By following these steps, you should be able to resolve the permission issue and successfully start your Flask container. If you encounter any more errors or issues, feel free to ask!

getting an error sir , requirment.txt file does not exist how to resolve this ?
