🌍 πŸ“‹ A web dashboard to inspect Terraform States

Docker Pulls Go Report Card Gitter Build Status Coverage Status By Camptocamp Documentation

Website: https://terraboard.io


Caution: Terraboard's Docker registry was migrated from Dockerhub to GHCR! All new tags will be now pushed here. You can still access to old tags on the legacy Dockerhub repository.

Table of content

What is it?

Terraboard is a web dashboard to visualize and query Terraform states. It currently features:

  • an overview page listing the most recently updated state files with their activity
  • a state page with state file details, including versions and resource attributes
  • a search interface to query resources by type, name or attributes
  • a diff interface to compare state between versions

It currently supports several remote state backend providers:

Terraboard is now able to handle multiple buckets/providers configuration! πŸ₯³ Check configuration section for more details.

Overview

The overview presents all the state files in the S3 bucket, by most recent modification date.

Screenshot Overview

Search

The search view allows to find resources by various criteria.

State

The state view presents details of a Terraform state at a given version.

Compare

From the state view, you can compare the current state version with another version.

Requirements

Independently of the location of your statefiles, Terraboard needs to store an internal version of its dataset. For this purpose it requires a PostgreSQL database. Data resiliency is not paramount though as this dataset can be rebuilt upon your statefiles at anytime.

AWS S3 (state) + DynamoDB (lock)

  • A versioned S3 bucket name with one or more Terraform states, named with a .tfstate suffix
  • AWS credentials with the following IAM permissions over the bucket:
    • s3:GetObject
    • s3:ListBucket
    • s3:ListBucketVersions
    • s3:GetObjectVersion
  • If you want to retrieve lock states from a dynamoDB table, you need to make sure the provided AWS credentials have dynamodb:Scan access to that table.

Terraform Cloud

  • Account on Terraform Cloud
  • Existing organization
  • Token assigned to an organization

Configuration

Terraboard currently supports configuration in three different ways:

  1. Environment variables (only usable for single provider configuration)
  2. CLI parameters (only usable for single provider configuration)
  3. Configuration file (YAML). A configuration file example can be found in the root directory of this repository and in the test/ subdirectory.

Important: all flags/environment variables related to the providers settings aren't compatible with multi-provider configuration! Instead, you must use the YAML config file to be able to configure multiples buckets/providers. YAML config is able to load values from environments variables.

The precedence of configurations is as described below.

Multiple buckets/providers

In order for Terraboard to import states from multiples buckets or even providers, you must use the YAML configuration method:

  • Set the CONFIG_FILE environment variable or the -c/--config-file flag to point to a valid YAML config file.
  • In the YAML file, specify your desired providers configuration. For example with two MinIO buckets (using the AWS provider with compatible mode):
# Needed since MinIO doesn't support versioning or locking
provider:
  no-locks: true
  no-versioning: true

aws:
  - endpoint: http://minio:9000/
    region: ${AWS_DEFAULT_REGION}
    s3:
      - bucket: test-bucket
        force-path-style: true
        file-extension:
          - .tfstate

  - endpoint: http://minio:9000/
    region: eu-west-1
    s3:
      - bucket: test-bucket2
        force-path-style: true
        file-extension:
          - .tfstate

In the case of AWS, don't forget to set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

That's it! Terraboard will now fetch these two buckets on DB refresh. You can also mix providers like AWS and Gitlab or anything else. You can find a ready-to-use Docker example with two MinIO buckets in the test/multiple-minio-buckets/ sub-folder.

Push plans to Terraboard

In order to send Terraform plans to Terraboard, you must wrap it in this JSON format:

{
    "lineage": "<Plan's lineage>",
    "terraform_version": "<Terraform version>",
    "git_remote": "<The URL of the remote that generated this plan>",
    "git_commit": "<Commit hash>",
    "ci_url": "<The URL of the CI that sent this plan>",
    "source": "<Free field for the triggering event>",
    "plan_json": "<Terraform plan JSON export>"
}

And send it to /api/plans using POST method

Use with Docker

Docker-compose

Configuration file can be provided to the container using a volume or a configuration.

# Set AWS credentials as environment variables:
export AWS_ACCESS_KEY_ID=<access_key>
export AWS_SECRET_ACCESS_KEY=<access_secret>

# Set AWS configuration as environment variables:
export AWS_DEFAULT_REGION=<AWS default region>
export AWS_BUCKET=<S3 Bucket name>
export AWS_DYNAMODB_TABLE=<Aws DynamoDB Table>

docker-compose up

Then point your browser to http://localhost:8080.

Docker command line

# Set AWS credentials as environment variables:
export AWS_ACCESS_KEY_ID=<access_key>
export AWS_SECRET_ACCESS_KEY=<access_secret>

# Set AWS configuration as environment variables:
export AWS_DEFAULT_REGION=<AWS default region>
export AWS_BUCKET=<S3 Bucket name>
export AWS_DYNAMODB_TABLE=<AWS_DYNAMODB_TABLE>

# Spin up the two containers and a network for them to communciate on:
docker network create terraboard
docker run --name db \
  -e POSTGRES_USER=gorm \
  -e POSTGRES_DB=gorm \
  -e POSTGRES_PASSWORD="<mypassword>" \
  -e GODEBUG="netdns=go" \
  --net terraboard \
  --detach \
  --restart=always \
  postgres:9.5

docker run -p 8080:8080 \
  -e AWS_ACCESS_KEY_ID="${AWS_ACCESS_KEY_ID}" \
  -e AWS_SECRET_ACCESS_KEY="${AWS_SECRET_ACCESS_KEY}" \
  -e AWS_REGION="${AWS_DEFAULT_REGION}" \
  -e AWS_BUCKET="${AWS_BUCKET}" \
  -e AWS_DYNAMODB_TABLE="${AWS_DYNAMODB_TABLE}" \
  -e DB_PASSWORD="<mypassword>" \
  -e DB_SSLMODE="disable" \
  --net terraboard \
  ghcr.io/camptocamp/terraboard:latest

Then point your browser to http://localhost:8080.

Use with Kubernetes

A Helm chart is available on Camptocamp's repository.

In order to install it:

$ helm repo add c2c https://camptocamp.github.io/charts
$ helm install -v values.yaml terraboard c2c/terraboard

Use with Rancher

Camptocamp's Rancher Catalog contains a Terraboard template to automate its installation in Cattle.

Authentication and base URL

Terraboard does not implement authentication. Instead, it is recommended to use an authentication proxy such as oauth2_proxy.

If you need to set a route path for Terraboard, you can set a base URL by passing it as the BASE_URL environment variable.

When using an authentication proxy, Terraboard will retrieve the logged in user and email from the headers passed by the proxy. Terraboard expects you to setup the HTTP Headers X-Forwarded-User and X-Forwarded-Email when passing the logged in user and email. A Nginx example can be found below:

location / {
  ....
  auth_request_set $user   $upstream_http_x_auth_request_user;
  auth_request_set $email  $upstream_http_x_auth_request_email;
  proxy_set_header X-Forwarded-User  $user;
  proxy_set_header X-Forwarded-Email $email;
  ...
  proxy_pass http://terraboard/;
}

You can also pass a TERRABOARD_LOGOUT_URL parameter to allow users to sign out of the proxy.

Install from source

$ go get github.com/camptocamp/terraboard

Development

Architecture

Terraboard is made of two components:

A server process

The server is written in go and runs a web server which serves:

  • the API on known access points, taking the data from the PostgreSQL database
  • the index page (from static/index.html) on all other URLs

The server also has a routine which regularly (every 1 minute) feeds the PostgreSQL database from the S3 bucket.

A web UI

The UI is an AngularJS application served from index.html. All the UI code can be found in the static/ directory.

Testing

$ docker-compose build && docker-compose up -d
# Point your browser to http://localhost
