OnDemandMinecraft-Mirrored | An AWS hosted Minecraft server that will only run when players are active. Players can start the ser

This step will properly configure your AWS account and ec2_conf.yml so that an instance can be created via the server.py script (using the flag -r create_instance).
Create or access an AWS Account. Under the User Dropdown in the Toolbar, select Security Credentials, then Access Keys, and finally Create New Access Key. Download this file, open it, and copy the values of AWSAccessKeyId and AWSSecretKey to access_key and secret_key in the ec2_conf.yml file. aws: - config: access_key: YourAWSAccessKeyIdHere # Modify this secret_key: YourAWSSecretKeyHere # Modify this ............................................................
Navigate to the EC2 Dashboard under the Services Dropdown and select Security Groups in the sidebar. Select Create Security Group, input minecraft for the Security group name. Create Inbound Rules for the following: Type: SSH Protocol: TCP Port Range: 22 Source: Anywhere Type: Custom TCP Rule Protocol: TCP Port Range: 25565 Source: Anywhere Type: Custom UDP Rule Protocol: UDP Port Range: 25565 Source: Anywhere In ec2_conf.yml, set ec2_secgroups to the name of the security group. aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere ec2_secgroups: - YourGroupNameHere # Modify this ............................................................
Under the EC2 Dashboard navigate to Key Pairs in the sidebar. Select Create Key Pair, provide a name and create. Move the file that is downloaded into the ./keys directory in the project. In ec2_conf.yml, set ec2_keypair to the name entered, and ssh_key_file_name to the name.pem of the file downloaded. THIS MIGHT BE SUBJECT TO CHANGE aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName # Modify this mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem # Modify this ............................................................ You have also the option to upload the key to Dropbox in order to keep it hidden from the repo. See the Dropbox Setup section.
This step is concerned with creating the AWS instance. View https://docs.aws.amazon.com/general/latest/gr/rande.html (Or google AWS Regions), and copy the Region column for the Region Name of where you wish to host your server. In ec2_conf.yml, set the ec2_region variable to the copied value. aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName ec2_region: Your-Region-Here # Modify this mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem ............................................................
Navigate to https://aws.amazon.com/ec2/instance-types/ and select one of the T3 types (with the memory and CPU you desire, I recommend 10 players/GB). Copy the value in the Model column. I've configured mine to use t3.small. In ec2_conf.yml, set the ec2_instancetype variable to the copied value. aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName ec2_region: Your-Region-Here ec2_instancetype: t3.yourSizeHere # Modify this mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem ............................................................
Then we must select an image for the instance to boot. Navigate to https://cloud-images.ubuntu.com/locator/ec2/, in the filter at the bottom of the screen, select your region of choice under Zone, pick any LTS (Latest Stable) under Version, under Arch select amd64, and hvm:ebs under Instance Type. Select one of the images available and copy the AMI-ID. In ec2_conf.yml, set the ec2_amis variable to the copied value. aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName ec2_region: Your-Region-Here ec2_instancetype: t3.yourSizeHere ec2_amis: - ami-YourImageIdHere # Modify this mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem ............................................................
At this point you should have the necessary configuration to create a new instance through the server.py script (using the flag -r create_instance flag) in the root folder. Open a command line in the root directory of the project, and execute: pip install -r requirements.txt After successful installation of dependencies execute: python server.py -r create_instance -c configs/ec2_conf.yml Copy the Instance ID that is output into the terminal. In ec2_conf.yml, set the instance_id variable to the copied value. aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere instance_id: i-yourInstanceIdHere # Modify this ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName ec2_region: Your-Region-Here ec2_instancetype: t3.yourSizeHere ec2_amis: - ami-YourImageIdHere mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem ............................................................
In this step, you have the option to use Dropbox in order to upload your ssh key file there for it to be hidden from the Github repo and at the same time available for download from Heroku when needed. You can skip this step if you you want to use a private repository.
Setup a Dropbox account if you haven't already.
Create an Api Key for your Dropbox account.
Add the cloudstore section in the ec2_conf.yml file: aws: - config: access_key: YourAWSAccessKeyIdHere secret_key: YourAWSSecretKeyHere instance_id: i-yourInstanceIdHere ec2_secgroups: - YourGroupNameHere ec2_keypair: YourKeyPairName ec2_region: Your-Region-Here ec2_instancetype: t3.yourSizeHere ec2_amis: - ami-YourImageIdHere mineserver: - config: ssh_key_file_path: ./keys/YourKeyFileName.pem web_client: - config: server_password: YourPasswordHere # Modify this cloudstore: - config: api_key: !ENV ${DROPBOX_API_KEY} # Modify this remote_folder: OnDemandMinecraft # Modify this ............................................................
Set an os variable for the Dropbox api key (as described in the 5th step of the previous section) and modify the corresponding section in the ec2_conf.yml file.
Do the same for the remote_folder which represents tha name of the Dropbox in which the ssh key file will be stored.
Lastly, after placing the ssh key file in the keys folder, upload the file by executing: python server.py -c configs/ >.yml -r upload_key_file
