Dottie

About

dottie (dot ⚫ tie 👔 or dotty) is a tool for working with dot-env (.env) files more enjoyable and safe.

• Grouping of keys into logical sections
• Rich validation of key/value pairs via comment "annotations"
• Update/sync/migrate a .env file from an upstream/external source for easy upgrades/migrations.
• Create/Read/Update/Delete commands for easy programmatic manipulation of the .env file.
• JSON representation of the .env file for templating or external consumption.
• Enable (uncomment) and Disable (comment) KEY/VALUE pairs.
• Colorized / pretty / dense / export output.
• Filtering by key/prefix/groups when printing keys.
• Literal (what you see is what you get) or interpolated (shell-like interpolation of variables) modes.

Example

Warning

Run these example commands in a directory without an existing .env file

# Crate a new env file
touch .env

# Create a key/pair value
dottie set my_key=value

# Create another key (PORT) with value "3306"
#  * One comment
#  * One validation rule that the value must be a number
#  * "none" quote style from the default "double"
dottie set \
  --comment 'A port for some service' \
  --comment '@dottie/validate number' \
  --quote-style none \
  PORT=3306

# Check validation (success)
dottie validate

# Print the file
dottie print

# Print the file (but pretty)
dottie print --pretty

# Change the "PORT" value to a "test" (a non-number).
# NOTE: the comments are kept in the file, even if they are omitted here
dottie set PORT=test

# Test validation again (it now fails)
dottie validate

# Fix the port value
dottie set PORT=3306

# Create a new key/value pair in a group named "database"
# NOTE: the group will be created on-demand if it does not exists
dottie set \
  --group database \
  --comment 'the hostname to the database' \
  DB_HOST="db"

# Create a "DB_PORT" key pair in the same "database" group as before
# NOTE: this value refer to the 'PORT' key we set above via interpolation
dottie set \
  --group database \
  --comment 'the port for the database' \
  --comment '@dottie/validate number' \
  DB_PORT='${PORT}'

# Print the file again
dottie print --pretty

# Disable the DB_PORT key
dottie disable DB_PORT

# Print the file again
# NOTE: the DB_PORT key/value is now gone
dottie print --pretty

# Print the file again, but include commented disabled keys
# NOTE: the DB_PORT key/value is printed (but still disabled)
dottie print --pretty --with-disabled

# Enable the DB_PORT key again
dottie enable DB_PORT

Verifying the artifacts

binaries

All artifacts are checksummed, and the checksum file is signed with cosign.

1. Download the files you want, and the checksums.txt, checksum.txt.pem and checksums.txt.sig files from the releases page:

2. Verify the signature:

   cosign verify-blob \
     --certificate-identity 'https://github.com/jippi/dottie/.github/workflows/release.yml@refs/tags/v1.0.0' \
     --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
     --cert 'https://github.com/jippi/dottie/releases/download/v1.0.0/checksums.txt.pem' \
     --signature 'https://github.com/jippi/dottie/releases/download/v1.0.0/checksums.txt.sig' \
     ./checksums.txt

3. If the signature is valid, you can then verify the SHA256 sums match with the downloaded binary:

   sha256sum --ignore-missing -c checksums.txt

docker images

Our Docker images are signed with cosign.

Verify the signatures:

cosign verify \
  --certificate-identity 'https://github.com/jippi/dottie/.github/workflows/release.yml@refs/tags/v1.0.0' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  jippi/dottie

Note

The .pem and .sig files are the image name:tag, replacing / and : with -.
