The easiest way to deploy a Spring Boot application to the cloud is using AWS EC2. In this video I will show how to deploy a simple web application to EC2 in such a way it can be used from a CI/CD platform to upload a new version each time it's available.

Thank you so much! This made so many things clear to me. I worked with several old ways to manage my projects. From hosting my own servers (about 20 years ago) to some docker managed instances and so on. AWS was a misterium for me. So many things you can do there but you brought it to the point for me. EC2 is only a virtual machine :) And the networking is also only networking VPC (virtual private cnetwork ;))

Hi! Your video is excellent and is helping me a lot during my final project at college. However, I can't run the command "mvn" on my terminal (command not found). I also have a maven spring boot project, but I don't get what I did wrong. Would you help me, please?

@TheDevWorldbySergioLema Год назад

Thanks. The "mvn" command is the Maven command. If you don't have it installed in your EC2 image, you can also use the Maven Wrapper in many Spring Boot projects (which doesn't need to install).

Check your security group. I must at least accept the port 22 for SSH and port 80 for ping.

You have many ways to generate ssh keys. It depends on your OS. On windows, you have OpenSSH or Putty. On Linux or MacOS, you have ssh-keygen.

Merci pour la vidéo Sergio. Tu crée une nouvelle instance EC2 pour le CI/CD, mais comment arrêter, effacer ton ancienne instance et transférer les requêtes vers la nouvelle vm pour ne pas utiliser trop de ressources lors du déploiement?

@TheDevWorldbySergioLema 4 месяца назад

Merci pour ton commentaire Bruno. Là tu parles d'un cas plus avancé. En utilisant uniquement EC2, tu peux réussir ça en mettant un Load Balancer devant ton instance EC2. Quand tu crée ta nouvelle instance, il faudra la déclarer dans le Load Balancer. Et quand ru supprime l'ancienne, elle sera automatiquement supprimée du Load Balancer. Et le Load Balancer se chargera de rediriger le traffic d'une instance à l'autre.

@oss2046 9 месяцев назад

Is it possible to do the same but with a war file instead of a jar file?

@TheDevWorldbySergioLema 9 месяцев назад

With a war file, you nees to first install a web server like Tomcat or Glassfish. The rest is the same (EC2 creation, security groups, VPN...)

@exerazor1911 Год назад

i was having the same error, make sure that you are running the scp command on your local machine and not while connected to the ec2 instance :)

You must use the same user ec2-user when copying the JAR file, "scp file.jar ec2-user@MY_IP:/home/ec2-user/"

@muadgra3545 3 месяца назад

I encountered problems (I'm using windows), you can also use EC2 console to connect

@TheDevWorldbySergioLema 3 месяца назад

Yes, the AWS console is very useful, as you don't need to configure your computer

@naziashaikh998 4 месяца назад

The worst part is some things are already configured at tutors end, like console, terminal etc, and we are not sure how did tutor set them up in first place ;( . also, having lengthy commands pasted in description would make it easier for us to simple copy paste and do the job :)

@TheDevWorldbySergioLema 4 месяца назад

Sorry for not copy-past the commands on the description, but RU-vid don't render well some commands as it thinks it's some Script injection attack. The only thing I have previously configured, is the aws configure to create a profile connected to my AWS account. You can check how to do it here: docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html#cli-configure-files-using-profiles

@40ozhemlock 9 дней назад

Sorry I'm dumb. When you say "and go to a terminal" (to connect to the instance). Do you mean just the command line on my local machine? Or are you talking about something in AWS? Doesn't AWS provide like 3 different ways within the console to connect to the instance? What do you mean when you say "and go to a terminal"?

@40ozhemlock 9 дней назад

tried it from the command line.... permission denied....

@TheDevWorldbySergioLema 9 дней назад

Go to your local machine terminal. But you need to configure it before. Check here how to do it: docs.aws.amazon.com/cli/v1/userguide/cli-chap-configure.html

@welbe9436 Год назад

how did you add ssh key and what is ssh key, where to find that?

@TheDevWorldbySergioLema Год назад

An SSH keys is like a username/password to let your computer connecter to another computer via the port 22. You can generate them with ssh-keygen, putty or other tools. You must first generate a public/private key in your computer, then upload in the Key Pairs section of AWS the public one. Then, you can connect to the EC2 instances which have your Key Pair.

@mrowox Год назад

@@TheDevWorldbySergioLema I have generated my key-pair, uploaded the public one to was and I still cannot connect. the error is `Permission denied (publickey,gssapi-keyex,gssapi-with-mic).`

@TheDevWorldbySergioLema Год назад

Maybe your SSH key has permissions too open. Maybe the route to your SSH key is not the default one and your SSH agent can't find it. Check this link and try add the verbose option to see more details about the error: askubuntu.com/questions/311558/ssh-permission-denied-publickey

@sachinthanaaluvihare7961 6 месяцев назад

If you get Permission denied (publickey,gssapi-keyex,gssapi-with-mic) when tring to ssh to ec2-user, just run chmod 400 on the pem file and try again

How do you do this on windows CMD?

@TheDevWorldbySergioLema 5 месяцев назад

The goal of those commands is to run them from a CI/CD platform like GitlabCI. I've never used Windows on a CI/CD platform. But the AWS CLI is the same for Windows. You can check the installation guide in the official AWS Console page.

@anmarhammadi7471 3 дня назад

oh right so we should be using the AWS cli here not windows CMD prompt. I think a few people are confused as to what shell was used in this video to run the command ssh ec2-user@blablabla

@kanagasingamdanushan3701 Год назад

Why can't access end points after closed the terminal?

@TheDevWorldbySergioLema Год назад

In my case, I run the Spring Boot application in the terminal, not in a background task. If I close the terminal which is running the application, it stops. For production ready applications, you should configure the startup of your application in the User Details script. This way, it's running as soon as the instance is up.

how to keep it running even after ssh session is terminated and my pc is shutdown? the app shuts down after a while

@TheDevWorldbySergioLema Год назад

You can simply run it in background. Add the & symbol at the end of the command, and it will run in the background. Or create a screen and run it in the screen. Either way, when closing the SSH session, the application still runs.

@elitemiro Год назад

@@TheDevWorldbySergioLema it still shuts down when i close the terminal i need to run like a dedicated server

@TheDevWorldbySergioLema Год назад

I'm not sure about what you mean about '"close the terminal". When running the server, you must add the "&" symbol at the end of the command. Then, you should have the terminal free to continue. Exploring the processes, ps -a, you should see the previous server running. Then, close the SSH connection and the server must continue to run. If the "&" symbol doesn't work, try using a screen (linuxize.com/post/how-to-use-linux-screen/).
