Caddy is an extensible server platform that uses TLS by default. This guide walks you through setting up, deploying, and launching the Caddy web server on the Akash Network. We’ll use the official Docker image for Caddy and leverage your provided SDL template to craft the deployment configuration.
Prerequisites
- Install Akash CLI: Follow the official guide to set up the Akash CLI.
- Create an Akash Wallet: If you don’t already have an Akash wallet, use the wallet creation guide to set one up.
- Fund Your Wallet: Fund your Akash wallet with AKT tokens to pay for deployments.
- Install Docker: Ensure Docker is installed and running on your local machine.
- Install a Code Editor: Use an editor like VSCode for editing SDL files.
Step 1: Prepare the SDL File (deploy.yaml)
Below is an example SDL file (deploy.yaml) for deploying Caddy using its official Docker image:
---version: "2.0"
services: caddy: image: caddy:latest env: - CADDY_HOST=:80 expose: - port: 80 to: - global: true
profiles: compute: caddy: resources: cpu: units: 0.25 memory: size: 512Mi storage: size: 1Gi
placement: akash: attributes: region: us-west pricing: caddy: denom: uakt amount: 500
deployment: caddy: akash: profile: caddy count: 1
Notes:
- image: Uses the official Caddy Docker image.
- port: Caddy listens on port 80 globally.
- resources: Allocates minimal CPU, memory, and storage resources.
- pricing: Defines a base price for deployment.
Step 2: Deploy Using Akash CLI
- Create your Certificate
Akash requires an account to have a valid certificate associated with it to start participating in the deployment process. In this section of the guide, we will create a certificate locally, and then proceed to store this certificate on the Akash blockchain. To do this, ensure you have followed all the steps outlined in this guide up to this point. Additionally, these transactions must be executed from an Akash account in possession of some $AKT tokens.
Once an account has a certificate associated with it, it can begin deploying services on the Akash blockchain. A certificate needs to be created only once per account. After creation, it can be used across any number of deployments for as long as it remains valid.
provider-services tx cert generate client -from $AKASH_KEY_NAME
- Publish Cert to the Blockchain
provider-services tx cert publish client -from $AKASH_KEY_NAME
-
Create your Deployment
-
CPU Support
Only x86_64 processors are officially supported for Akash deployments. This may change in the future and when ARM processors are supported it will be announced and documented.
- Akash Deployment
NOTE - if your current terminal session has been used to create prior deployments, issue the command
unset AKASH_DSEQ
to prevent receipt of error messageDeployment Exists
To deploy on Akash, run:
provider-services tx deployment create deploy.yaml -from $AKASH_KEY_NAME
You should see a response similar to:

- Find your Deployment -
Find the Deployment Sequence (DSEQ) in the deployment you just created. You will need to replace the AKASH_DSEQ with the number from your deployment to configure a shell variable.
export AKASH_DSEQ=CHANGETHIS
Now set the Order Sequence (OSEQ) and Group Sequence (GSEQ). Note that if this is your first time deploying on Akash, OSEQ and GSEQ will be 1.
AKASH_OSEQ=1AKASH_GSEQ=1
Verify we have the right values populated by running:
echo $AKASH_DSEQ $AKASH_OSEQ $AKASH_GSEQ
- View your Bids
After a short time, you should see bids from providers for this deployment with the following command:
provider-services query market bid list -owner=$AKASH_ACCOUNT_ADDRESS -node $AKASH_NODE -dseq $AKASH_DSEQ -state=open
- Choose a Provider
Note that there are bids from multiple different providers. In this case, both providers happen to be willing to accept a price of 1 uAKT. This means that the lease can be created using 1 uAKT or 0.000001 AKT per block to execute the container. You should see a response similar to:
bids:- bid: bid_id: dseq: "140324" gseq: 1 oseq: 1 owner: akash1vn06ycjjnvsvl639fet9lajjctuturrtx7fvuj provider: akash10cl5rm0cqnpj45knzakpa4cnvn5amzwp4lhcal created_at: "140326" price: amount: "1" denom: uakt state: open escrow_account: balance: amount: "50000000" denom: uakt id: scope: bid xid: akash1vn06ycjjnvsvl639fet9lajjctuturrtx7fvuj/140324/1/1/akash10cl5rm0cqnpj45knzakpa4cnvn5amzwp4lhcal owner: akash10cl5rm0cqnpj45knzakpa4cnvn5amzwp4lhcal settled_at: "140326" state: open transferred: amount: "0" denom: uakt- bid: bid_id: dseq: "140324" gseq: 1 oseq: 1 owner: akash1vn06ycjjnvsvl639fet9lajjctuturrtx7fvuj provider: akash1f6gmtjpx4r8qda9nxjwq26fp5mcjyqmaq5m6j7 created_at: "140326" price: amount: "1" denom: uakt state: open escrow_account: balance: amount: "50000000" denom: uakt id: scope: bid xid: akash1vn06ycjjnvsvl639fet9lajjctuturrtx7fvuj/140324/1/1/akash1f6gmtjpx4r8qda9nxjwq26fp5mcjyqmaq5m6j7 owner: akash1f6gmtjpx4r8qda9nxjwq26fp5mcjyqmaq5m6j7 settled_at: "140326" state: open transferred: amount: "0" denom: uakt
For this example, we will choose akash10cl5rm0cqnpj45knzakpa4cnvn5amzwp4lhcal
Run this command to set the provider shell variable:
AKASH_PROVIDER=akash10cl5rm0cqnpj45knzakpa4cnvn5amzwp4lhcal
Verify we have the right value populated by running:
echo $AKASH_PROVIDER
- Create a Lease
Create a lease for the bid from the chosen provider above by running this command:
provider-services tx market lease create -dseq $AKASH_DSEQ -provider $AKASH_PROVIDER -from $AKASH_KEY_NAME
- Confirm the Lease
You can check the status of your lease by running:
provider-services query market lease list -owner $AKASH_ACCOUNT_ADDRESS -node $AKASH_NODE -dseq $AKASH_DSEQ
Note the bids will close automatically after 5 minutes, and you may get the response:
bid not open
If this happens, close your deployment and open a new deployment again. To close your deployment run this command:
provider-services tx deployment close -dseq $AKASH_DSEQ -owner $AKASH_ACCOUNT_ADDRESS -from $AKASH_KEY_NAME
If your lease was successful you should see a response that ends with:
state: active
{/* {% hint style=“info” %} /} Please note that once the lease is created, the provider will begin debiting your deployment’s escrow account, even if you have not completed the deployment process by uploading the manifest in the following step. {/ {% endhint %} */}
- Send the Manifest
Upload the manifest using the values from above step:
provider-services send-manifest deploy.yaml -dseq $AKASH_DSEQ -provider $AKASH_PROVIDER -from $AKASH_KEY_NAME
- Confirm the URL
Now that the manifest is uploaded, your image is deployed. You can retrieve the access details by running the below:
provider-services lease-status -dseq $AKASH_DSEQ -from $AKASH_KEY_NAME -provider $AKASH_PROVIDER
You should see a response similar to:
{ "services": { "web": { "name": "web", "available": 1, "total": 1, "uris": [ "rga3h05jetf9h3p6dbk62m19ck.ingress.ewr1p0.mainnet.akashian.io" ], "observed_generation": 1, "replicas": 1, "updated_replicas": 1, "ready_replicas": 1, "available_replicas": 1 } }, "forwarded_ports": {}}
You can access the application by visiting the hostnames mapped to your deployment. Look for a URL/URI and copy it to your web browser.
- View your logs
You can view your application logs to debug issues or watch progress like so:
provider-services lease-logs \ -dseq "$AKASH_DSEQ" \ -provider "$AKASH_PROVIDER" \ -from "$AKASH_KEY_NAME"
-
Update the Deployment
-
Update the Manifest
Update the deploy.yaml manifest file with the desired change.
NOTE:** Not all attributes of the manifest file are eligible for deployment update. If the hardware specs of the manifest are updated (I.e. CPU count), a re-deployment of the workload is necessary. Other attributes, such as deployment image and funding, are eligible for updates.
- Issue Transaction for On Chain Update
provider-services tx deployment update deploy.yaml -dseq $AKASH_DSEQ -from $AKASH_KEY_NAME
- Send Updated Manifest to Provider
provider-services send-manifest deploy.yaml -dseq $AKASH_DSEQ -provider $AKASH_PROVIDER -from $AKASH_KEY_NAME
For detailed steps on using the CLI, refer to the Akash CLI Deployment Guide.
