Registration and setup

Estuary Flow is a fully managed web application that also offers a robust CLI. Once you register in the web application, you can seamlessly use either or both tools to do your work.

Get started with the Flow web application

To start using Flow for free, visit the web application. See what the free tier includes on the Pricing page.

When you register for Flow, your account will use Flow's secure cloud storage bucket to store your data. Data in Flow's cloud storage bucket is deleted 30 days after collection.

For production use cases, you should configure your own cloud storage bucket to use with Flow.

Get started with the Flow CLI

After your account has been activated through the web app, you can begin to work with your data flows from the command line. This is not required, but it enables more advanced workflows or might simply be your preference.

Flow has a single binary, flowctl.

flowctl is available for:

  • Linux x86-64. All distributions are supported.
  • MacOS 11 (Big Sur) or later. Both Intel and M1 chips are supported.

To install, copy and paste the appropriate script below into your terminal. This will download flowctl, make it executable, and add it to your PATH.

  • For Linux:
sudo curl -o /usr/local/bin/flowctl -L 'https://github.com/estuary/flow/releases/latest/download/flowctl-x86_64-linux' && sudo chmod +x /usr/local/bin/flowctl
  • For Mac:
sudo curl -o /usr/local/bin/flowctl -L 'https://github.com/estuary/flow/releases/latest/download/flowctl-multiarch-macos' && sudo chmod +x /usr/local/bin/flowctl

Alternatively, Mac users can install with Homebrew:

brew tap estuary/flowctl
brew install flowctl

flowctl isn't currently available for Windows. For Windows users, we recommend running the Linux version inside WSL, or using a remote development environment.

The flowctl source files are also on GitHub here.

Once you've installed flowctl and are ready to begin working, authenticate your session using an access token.

  1. Ensure that you have an Estuary account and have signed into the Flow web app before.

  2. In the terminal of your local development environment, run:

    flowctl auth login

    In a browser window, the web app opens to the CLI-API tab.

  3. Copy the access token.

  4. Return to the terminal, paste the access token, and press Enter.

The token will expire after a predetermined duration. Repeat this process to re-authenticate.

Configuring your cloud storage bucket for use with Flow

New Flow accounts are connected to Flow's secure cloud storage bucket to store collection data. To switch to your own bucket, choose a cloud provider and complete the setup steps:

Once you're done, get in touch.

Google Cloud Storage buckets

You'll need to grant Estuary Flow access to your GCS bucket.

  1. Create a bucket to use with Flow, if you haven't already.

  2. Follow the steps to add a principal to a bucket level policy. As you do so:

    • For the principal, enter flow-258@helpful-kingdom-273219.iam.gserviceaccount.com

    • Select the roles/storage.admin role.

Amazon S3 buckets

Your bucket must be in the us-east-1 region. You'll need to grant Estuary Flow access to your S3 bucket.

  1. Create a bucket to use with Flow, if you haven't already.

  2. Follow the steps to add a bucket policy, pasting the policy below. Be sure to replace YOUR-S3-BUCKET with the actual name of your bucket.

{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AllowUsersToAccessObjectsUnderPrefix",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::789740162118:user/flow-aws"
},
"Action": ["s3:GetObject", "s3:PutObject", "s3:DeleteObject"],
"Resource": "arn:aws:s3:::YOUR-S3-BUCKET/*"
},
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::789740162118:user/flow-aws"
},
"Action": "s3:ListBucket",
"Resource": "arn:aws:s3:::YOUR-S3-BUCKET"
},
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::789740162118:user/flow-aws"
},
"Action": "s3:GetBucketPolicy",
"Resource": "arn:aws:s3:::YOUR-S3-BUCKET"
}
]
}

Azure Blob Storage

You'll need to grant Estuary Flow access to your storage account and container. You'll also need to provide some identifying information.

  1. Create an Azure Blob Storage container to use with Flow, if you haven't already.

  2. Gather the following information. You'll need this when you contact us to complete setup.

    • Your Azure AD tenant ID. You can find this in the Azure Active Directory page.

    • Your Azure Blob Storage account ID. You can find this in the Storage Accounts page.

    • Your Azure Blob Storage container ID. You can find this inside your storage account.

    You'll grant Flow access to your storage resources by connecting to Estuary's Azure application.

  3. Add Estuary's Azure application to your tenant.

  1. Grant the application access to your storage account via the Storage Blob Data Owner IAM role.

    • Inside your storage account's Access Control (IAM) tab, click Add Role Assignment.

    • Search for Storage Blob Data Owner and select it.

    • On the next page, make sure User, group, or service principal is selected, then click + Select Members.

    • You must search for the exact name of the application, otherwise it won't show up: Estuary Storage Mappings Prod

    • Once you've selected the application, finish granting the role.

    For more help, see the Azure docs.

Give us a ring

Once you've finished the above steps, contact us. Send support@estuary.dev an email with the name of the storage bucket and any other information you gathered per the steps above. Let us know whether you want to use this storage bucket to for your whole Flow account, or just a specific prefix. We'll be in touch when it's done!

Self-hosting Flow

The Flow runtime is available under the Business Source License. It's possible to self-host Flow using a cloud provider of your choice.

Beta

Setup for self-hosting is not covered in this documentation, and full support is not guaranteed at this time. We recommend using the hosted version of Flow for the best experience. If you'd still like to self-host, refer to the GitHub repository or the Estuary Slack.
