CouchDB

Apache CouchDB, often shortened to just “CouchDB”, is an open-source NoSQL database that uses JSON to store data, JavaScript as its query language using MapReduce, and HTTP for its API. It’s known for its ease of use, scalability, and fault-tolerant replication capabilities, making it a popular choice for distributed applications.

Setting Up Your Environment

Before deploying CouchDB on Akash, ensure you have the following prerequisites:

Akash Network Account: You should have an account on the Akash Network with sufficient AKT tokens to deploy the service.
Akash CLI or Console Access: Set up and configured on your machine.
Docker Knowledge: Familiarity with Docker is helpful.

Creating the SDL File

Below is a sample SDL file to deploy CouchDB using the official Docker image:

---
version: "2.0"

services:
  couchdb:
    image: couchdb
    env:
      - COUCHDB_USER=admin
      - COUCHDB_PASSWORD=password
    expose:
      - port: 5984
        as: 80
        to:
          - global: true

profiles:
  compute:
    couchdb:
      resources:
        cpu:
          units: 1.0
        memory:
          size: 1Gi
        storage:
          size: 1Gi
  placement:
    akash:
      attributes:
        host: akash
      signedBy:
        anyOf:
          - "akash1365yvmc4s7awdyj3n2sav7xfx76adc6dnmlx63"
      pricing:
        couchdb:
          denom: uakt
          amount: 10000

deployment:
  couchdb:
    akash:
      profile: couchdb
      count: 1

services: Defines the Docker image and port mapping.
profiles: Specifies the compute resources required (CPU, memory, and storage).
deployment: Sets the profile and instance count.

Save this file as deploy.yaml.

Deploying CouchDB on Akash

Using the CLI

Step 1: Authenticate with Akash

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 message Deployment 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=1
AKASH_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_id:
      dseq: "140324"

    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"
      ],

      "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 a more detailed CLI deployment guide, refer to Akash CLI Deployment Guide on the Akash documentation site.

Using the Console

If you prefer a UI-based approach, you can deploy CouchDB using the Akash Console:

Visit the Akash Console.
Sign in with your Keplr wallet.
Upload your deploy.yaml SDL file in the “Create Deployment” section.
Configure the deployment settings (similar to the CLI method).
Submit the deployment and fund it with the required AKT.
Monitor the deployment status via the console interface.

For more detailed instructions, you can refer to the Akash Console Guide.

Post-Deployment: Setting Up CouchDB

After your CouchDB instance is up and running:

Access the CouchDB Dashboard:

Use the IP or domain provided during the deployment.
The default port for CouchDB is 5984.

Secure CouchDB:

CouchDB is insecure by default. Set up an admin user by running the following command:

curl -X PUT http://<your-ip>:5984/_node/_local/_config/admins/admin -d '"password"'

Replace <your-ip> with your actual IP and password with your desired admin password.
