How to use

AWS

  • Create an IAM user with the following IAM policy:
wget https://komiser.s3.amazonaws.com/policy.json
  • Add your Access Key ID and Secret Access Key to ~/.aws/credentials using this format
[default]
aws_access_key_id = <access key id>
aws_secret_access_key = <secret access key>
region = <AWS region>
  • That should be it. Try out the following from your command prompt to start the server:
komiser start --port 3000

You can also use Redis as a caching server:

komiser start --port 3000 --redis localhost:6379 --duration 30

GCP

  • Create a service account with Viewer permission, see Creating and managing service accounts docs.

  • Enable the below APIs for your project through GCP Console, gcloud or using the Service Usage API. You can find out more about these options in Enabling an API in your GCP project docs.

    • appengine.googleapis.com
    • bigquery-json.googleapis.com
    • compute.googleapis.com
    • cloudfunctions.googleapis.com
    • container.googleapis.com
    • cloudresourcemanager.googleapis.com
    • cloudkms.googleapis.com
    • dns.googleapis.com
    • dataflow.googleapis.com
    • dataproc.googleapis.com
    • iam.googleapis.com
    • monitoring.googleapis.com
    • pubsub.googleapis.com
    • redis.googleapis.com
    • serviceusage.googleapis.com
    • storage-api.googleapis.com
    • sqladmin.googleapis.com
  • To analyze and optimize the infrastructure cost, you need to export your daily cost to BigQuery, see Export Billing to BigQuery docs.

  • Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS:

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
  • That should be it. Try out the following from your command prompt to start the server:
komiser start --port 3000 --dataset project-id.dataset-name.table-name

Options

komiser start [OPTIONS]
   --port value, -p value      Server port (default: 3000)
   --duration value, -d value  Cache expiration time (default: 30 minutes)
   --redis value, -r value     Redis server (localhost:6379)
   --dataset value, -ds value  BigQuery dataset name (project-id.dataset-name.table-name)

Configuring Credentials

When using the CLI with AWS, you'll generally need your AWS credentials to authenticate with AWS services. Komiser supports multiple methods of supporting these credentials. By default the CLI will source credentials automatically from its default credential chain.

  • Environment Credentials - Set of environment variables that are useful when sub processes are created for specific roles.

  • Shared Credentials file (~/.aws/credentials) - This file stores your credentials based on a profile name and is useful for local development.

  • EC2 Instance Role Credentials - Use EC2 Instance Role to assign credentials to application running on an EC2 instance. This removes the need to manage credential files in production.

When using the CLI with GCP, Komiser checks to see if the environment variable GOOGLE_APPLICATION_CREDENTIALS is set. If not an error occurs.
