secretexec

secretexec fetches a secret from AWS Secrets Manager and injects its key-value pairs as environment variables before executing a given command via execve(2). The current process is replaced by the target command — no wrapper process remains.

Requirements

  • Unix-like OS
  • AWS credentials available via the default credential chain (environment, ~/.aws, IAM role, etc.)

Usage

secretexec -s secret-id-or-arn /path/to/command [args...]

The secret must be a JSON object with string values, e.g.:

{
  "DB_PASSWORD": "hunter2",
  "API_KEY": "abc123"
}

Each key-value pair is injected into the environment of the executed command. Keys must consist only of ASCII letters, digits, hyphens, and underscores. Values must not contain Unicode control/format characters. Invalid entries are skipped with a warning.

If the command name contains no path separator, it is resolved via PATH lookup.

Example

secretexec -s myapp/production/env -- ./myapp --serve

Flags

-s — Secret name or ARN (required)

Notes

  • Execution timeout is 10 seconds (covers secret fetch only; the spawned process is not affected).
  • Binary secrets (SecretBinary) are not supported.
  • The program is Unix-only (//go:build unix).

Build

go build -o secretexec .
