Existing Kubernetes Cluster
Do you have a running Kubernetes cluster? If the answer is "yes," you can follow the guide below to become an Akash Cloud Provider. If your answer is "no," you can look at this document.
Check it! If you are using a newer systemd then your container will get stuck in ContainerCreating state on your provider with gVisor enabled.
- 1.A complete Kubernetes cluster.
- 2.Open the ssh port(usually 22) for the IP Addresses "68.250.12.64" (Praetor App's IP).
- 3.An existing Akash wallet with a minimum balance of 5 AKT.
- 4.Kubernetes config file of the cluster you want to provide.
- 5.A valid domain name where you can do DNS changes to point few domains to your cluster's machines / IP address.
To make sure your cluster is ready, please execute the following command.
[email protected]:~$ kubectl get nodes -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
node1 Ready control-plane,master 13d v1.23.6 10.0.10.114 <none> Debian GNU/Linux 10 (buster) 4.19.0-20-amd64 containerd://1.6.3
node2 Ready control-plane,master 13d v1.23.6 10.0.10.115 <none> Debian GNU/Linux 10 (buster) 4.19.0-20-amd64 containerd://1.6.3
node3 Ready <none> 13d v1.23.6 10.0.10.116 <none> Debian GNU/Linux 10 (buster) 4.19.0-20-amd64 containerd://1.6.3
Notice the CONTAINER-RUNTIME column's value must be "containered".
It would be best to ensure that the Kubernetes cluster's runtime class is "gVisor." Then, you can run the following command and verify.
Praetor App Home Page
Click on "Connect," It will ask you to connect your Akash wallet using the Keplr browser extension.
Note it! This address will be used to become the cloud provider in the network.
Connect your Keplr wallet with Praetor App
Keplr will request your permission to connect the wallet with Praetor App, Click Approve to continue.
Sign the arbitrary message to secure the communication with the backend service.
Keplr wallet will ask you to sign a message to generate an arbitrary signature. Then, the app will send it to the backend. We use this signature to make secure communication between the services.
Number of servers to be provided to Akash
Here, you can select the number of servers you want to provide to Akash. But, since you already have the Kubernetes cluster, you can click "Skip this step if you have Kubernetes."
This machine will be responsible for verifying installed Kubernetes and running the Akash service. Make sure this machine is available during this process.
The application needs to access your server to install Akash software. We also use your server to connect with your Kubernetes cluster. Praetor needs a user with sudo access to the device or root user to perform this. First, open the ssh port(usually 22) for the IP Addresses "185.209.177.59, 185.209.177.46, 185.209.176.35" (Praetor App's IP).
Hostname: Your server's hostname (either IP or web address without HTTP or HTTPS), If you use IP, then it must be your public IP address of IPv4 type
Username: Server username to login (e.g. root, admin, ubuntu, Debian etc.)
Password or File:
- If you select a password, then input the login password for the user.
- If the user selects a file, upload the ssh private key file. You can also provide a passphrase if your key file is encrypted.
Kube Config File: Upload a valid Kubernetes configuration file.
On clicking verify, the following pop-up screen will get open.
Is your Kubernetes cluster Akash ready?
This alert message asks you whether you have the necessary dependencies for Akash Network already installed or not. Akash Network's necessary dependencies are Akash Software, hostname operator, network policy and ingress nginx. On clicking "No," Akash Network dependencies will get installed on the server. "Yes," clicking indicates that all dependencies are already installed on the server and skips the Akash installation process.
Importing a wallet is necessary to run your provider and get lease AKT payouts.
Import Akash Wallet
Two ways to import your Akash wallet:
- 1.Praetor Mode(Recommended)
Praetor mode to import wallet
The app will verify your seed phrase with a connected wallet and create a Keystore file in your server.
Seed Phrase: Wallet Seed phrase (e.g. apple create carpet grain juice)
Password: 8 letter password of your choice. The app will use the password to encrypt the Keystore file.
Note! Please be noted that we use an end-to-end encryption method to transfer your seed phrase and password. So, you can be confident in typing your seed phrase here. Although, If you don’t want to provide your seed phrase here then you can switch to manual mode by “Switch to Manual Mode.”
2. Manual Mode:
Perform the following steps on your server.
(i) Login to the control machine using the username you used in the step-2
(ii) Create a Keyring file using the command
~/bin/akash — keyring-backend file keys add wallet_name — recover
(iii) Enter your mnemonic seed phrase and password
(iv) Run the following command and enter the same passphrase you have used in (ii)
echo {passphrase} > ~/.praetor/wallet_phrase_password.txt
Manual mode to import wallet
You are one more step closer to becoming a cloud provider for Akash Network.
Praetor Provider Configuration
On the Provider Configuration page, you will need to provide specific configurations. The app will use those values to make your provider on the chain, generate a server certificate and turn on provider service for Akash. From advance settings, you will also be able to set the pricing you wish to lease out your machine.
Provider domain: Domain name or public IP of the control machine (e.g. provider.praetorapp.com) Ingress domain: Domain or public IP of Kubernetes Ingress Controller node (e.g. ing.praetorapp.com)
Attribute Host Name: Unique name that represents your machine in Akash Network (e.g. Praetor App)
Advance Settings:
CPU Scale Bid Price: CPU scale pricing in uakt per milliCPU
Memory Scale Bid Price: Memory scale pricing in uakt per megabyte
Storage Scale Bid Price: Storage scale pricing in uakt per megabyte
Endpoint Scale Bid Price: Endpoint pricing in uakt
Bid Deposit: Bid deposit in uakt (e.g. 5000000 uakts = 5 AKTs)
After filling in all the necessary information, click on "Become Provider."
Become a provider loading screen
This screen will show you the progress of becoming an Akash cloud provider.
Congratulations you became a provider on Akash Network.
All the ports mentioned in the port table have to open for 0.0.0.0(Anywhere IPv4).
Ensure your provider domain and ingress domain point to the correct IP Address shown on the screen.
Port & DNS Configurations
They are security professionals trusted by Akash community members. They audit providers' technical proficiency and provide ensuring to your consumers for the service you cater.
Moultrie Audit(known as Akash-Audit)
If you click "Apply for Audit," The application will ask you to provide basic information.
On clicking "Skip," you will be redirected to the Dashboard.

Praetor Dashboard
Finally, You become a provider on Akash Network, and you will soon start getting leases on your machine. The Dashboard will provide information about your provider's server statistics and show how much is active, available and pending resources.
