Introduction

Up to the last time, we have launched EC2 Instance with boto3 x python. This time, let's install Code-Server on this launched Instance.

Try connecting with SSH

Let's operate the created EC Instance from cli

Get Instance information

You will need the Public IP information to make an ssh connection. You can get it with the following code.

def get_inst(ec2_client:ec2.Client, project_name="advent-code-server"):
    try:
        print(">>>> ec2client.describe_instances")
        res = ec2_client.describe_instances(Filters=[{"Name":"tag:Name","Values":[project_name]}])
        print("{}".format(res))

        for reserve_info in res['Reservations']:
            print("-")
            for instance_info in reserve_info['Instances']:
                print(">>>> {}".format(instance_info.get('InstanceId',"")))
                print(">>>> {}".format(instance_info.get('PublicDnsName',"")))
                print(">>>> {}".format(instance_info.get('PublicIpAddress',"")))
                print(">>>> {}".format(instance_info.get('PrivateDnsName',"")))
                print(">>>> {}".format(instance_info.get('PrivateIpAddress',"")))
                print(">>>> {}".format(instance_info.get('State',"")))
 
    except ClientError as e:
        print("-- {}".format(e.response))

ssh connect

Change the security of pem files

$ chmod 600 advent-code-server.pem

Connect to ec instance with ssh

$ ssh -i advent-code-server.pem [email protected]
root@dabe0caa28a0:/works/app# ssh -i advent-code-server.pem [email protected]

ubuntu@ip-10-1-0-227:~$

I was able to connect !!

Check if PORT is open! !!

Start static server

ubuntu@ip-10-1-0-227:~$ sudo apt-get install python3
ubuntu@ip-10-1-0-227:~$ python3 -m http.server 8080

Let's access it with a browser at http://18.182.61.231:8080/ !!

Seems to be working fine

Let's install Code-Server !!

ubuntu@ip-10-1-0-227:~$ wget https://github.com/cdr/code-server/releases/download/2.1692-vsc1.39.2/code-server2.1692-vsc1.39.2-linux-x86_64.tar.gz

ubuntu@ip-10-1-0-227:~$ tar -xzf code-server2.1692-vsc1.39.2-linux-x86_64.tar.gz -C ./ --strip-components 1

Let's run Code-Server !!

ubuntu@ip-10-1-0-227:~$ ./code-server --cert --port 8443 ./
on https://localhost:8443
info    - Password is 50cdee5af7ee7824126382ff
info      - To use your own password, set the PASSWORD environment variable
info      - To disable use `--auth none`
info    - Using generated certificate and key for HTTPS

Let's connect to https://18.182.61.231:8443/

I was able to start it safely !!

Supplement

In this state, if the SSH connection is lost, the application will end, so

ubuntu@ip-10-1-0-227:~$ ./code-server --cert --port 8443 ./&

Let's start it like this

Verification

buntu@ip-10-1-0-227:~$ jobs
[1]+  Running                 ./code-server --cert --port 8443 ./ &

When you want to finish

ubuntu@ip-10-1-0-227:~$ ps -aux | grep code-server
ubuntu    1786  0.2  5.2 840588 52580 ?        Sl   15:48   0:00 /home/ubuntu/code-server --cert --port 8443 ./
ubuntu    1918  0.0  0.0  14856  1004 pts/1    S+   15:51   0:00 grep --color=auto code-server

ubuntu@ip-10-1-0-227:~$ kill -9 1786

next time

Let's install Docker and launch the image created in the local version online
