Configurations

Read how to configure environment variables for self-hosted Infisical.

Infisical accepts all configurations via environment variables. For a minimal self-hosted instance, at least ENCRYPTION_KEY, AUTH_SECRET, DB_CONNECTION_URI and REDIS_URL must be defined. However, you can configure additional settings to activate more features as needed.

General platform

Used to configure platform-specific security and operational settings

ENCRYPTION_KEY · string · default: "none" · required

Must be a random 16 byte hex string. Can be generated with openssl rand -hex 16

AUTH_SECRET · string · default: "none" · required

Must be a random 32 byte base64 string. Can be generated with openssl rand -base64 32

SITE_URL · string · default: "none"

Must be an absolute URL including the protocol (e.g. https://app.infisical.com).

Data Layer

The platform utilizes Postgres to persist all of its data and Redis for caching and backgroud tasks

DB_CONNECTION_URI · string · default: "" · required

Postgres database connection string.

DB_ROOT_CERT · string · default: ""

Configure the SSL certificate for securing a Postgres connection by first encoding it in base64. Use the command below to encode your certificate: echo "<certificate>" | base64

REDIS_URL · string · default: "none" · required

Redis connection string.

Email service

Without email configuration, Infisical’s core functions like sign-up/login and secret operations work, but this disables multi-factor authentication, email invites for projects, alerts for suspicious logins, and all other email-dependent features.

Generic Configuration

SMTP_HOST · string · default: "none"

Hostname to connect to for establishing SMTP connections

SMTP_PORT · string · default: "587"

Port to connect to for establishing SMTP connections

SMTP_USERNAME · string · default: "none"

Credential to connect to host (e.g. [e-mail])

SMTP_PASSWORD · string · default: "none"

Credential to connect to host

SMTP_FROM_ADDRESS · string · default: "none"

Email address to be used for sending emails

SMTP_FROM_NAME · string · default: "none"

Name label to be used in From field (e.g. Team)

SMTP_IGNORE_TLS · bool · default: "false"

If this is true and SMTP_PORT is not 465 then TLS is not used even if the server supports STARTTLS extension.

SMTP_REQUIRE_TLS · bool · default: "true"

If this is true and SMTP_PORT is not 465 then Infisical tries to use STARTTLS even if the server does not advertise support for it. If the connection can not be encrypted then message is not sent.

SMTP_TLS_REJECT_UNAUTHORIZED · bool · default: "true"

If this is true, Infisical will validate the server’s SSL/TLS certificate and reject the connection if the certificate is invalid or not trusted. If set to false, the client will accept the server’s certificate regardless of its validity, which can be useful in development or testing environments but is not recommended for production use.

Twilio SendGrid

1. Create an account and configure SendGrid to send emails.
2. Create a SendGrid API Key under Settings > API Keys
3. Set a name for your API Key, we recommend using “Infisical,” and select the “Restricted Key” option. You will need to enable the “Mail Send” permission as shown below:

4. With the API Key, you can now set your SMTP environment variables:

SMTP_HOST=smtp.sendgrid.net
SMTP_USERNAME=apikey
SMTP_PASSWORD=SG.rqFsfjxYPiqE1lqZTgD_lz7x8IVLx # your SendGrid API Key from step above
SMTP_PORT=587
SMTP_FROM_ADDRESS=[e-mail] # your email address being used to send out emails
SMTP_FROM_NAME=Infisical

Remember that you will need to restart Infisical for this to work properly.

Mailgun

1. Create an account and configure Mailgun to send emails.
2. Obtain your Mailgun credentials in Sending > Overview > SMTP

3. With your Mailgun credentials, you can now set up your SMTP environment variables:

SMTP_HOST=smtp.mailgun.org # obtained from credentials page
SMTP_USERNAME=[e-mail] # obtained from credentials page
SMTP_PASSWORD=password # obtained from credentials page
SMTP_PORT=587
SMTP_FROM_ADDRESS=[e-mail] # your email address being used to send out emails
SMTP_FROM_NAME=Infisical

AWS SES

1. Create a verifed identity

   This will be used to verify the email you are sending from.

   If you AWS SES is under sandbox mode, you will only be able to send emails to verified identies.

2. Create an account and configure AWS SES

   Create an IAM user for SMTP authentication and obtain SMTP credentials in SMTP settings > Create SMTP credentials

   

   

3. Set up your SMTP environment variables

   With your AWS SES SMTP credentials, you can now set up your SMTP environment variables for your Infisical instance.

   SMTP_HOST=email-smtp.ap-northeast-1.amazonaws.com # SMTP endpoint obtained from SMTP settings
   SMTP_USERNAME=xxx # your SMTP username
   SMTP_PASSWORD=xxx # your SMTP password
   SMTP_PORT=465
   SMTP_FROM_ADDRESS=[e-mail] # your email address being used to send out emails
   SMTP_FROM_NAME=Infisical
   

Remember that you will need to restart Infisical for this to work properly.

SocketLabs

1. Create an account and configure SocketLabs to send emails.
2. From the dashboard, navigate to SMTP Credentials > SMTP & APIs > SMTP Credentials to obtain your SocketLabs SMTP credentials.

SMTP_PASSWORD=password # obtained from your credentials
SMTP_PORT=587
SMTP_FROM_ADDRESS=[e-mail] # your email address being used to send out emails
SMTP_FROM_NAME=Infisical

The SMTP_FROM_ADDRESS environment variable should be an email for an authenticated domain under Configuration > Domain Management in SocketLabs. For example, if you’re using SocketLabs in sandbox mode, then you may use an email like [e-mail].

Remember that you will need to restart Infisical for this to work properly.

Resend

Gmail

Create an account and enable “less secure app access” in Gmail Account Settings > Security. This will allow applications like Infisical to authenticate with Gmail via your username and password.

With your Gmail username and password, you can set your SMTP environment variables:

SMTP_HOST=smtp.gmail.com
SMTP_USERNAME=[e-mail] # your email
SMTP_PASSWORD=password # your password
