Installation

By downloading binary from the release

For instance, if you are using Linux on an AMD64 architecture:

# Download the binary
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.55.1/ytt-linux-amd64

Verify checksums file signature

The checksums file provided within the artifacts attached to this release is signed using Cosign with GitHub OIDC(Refer this page for cosign installation). To validate the signature of this file, run the following commands:

# Download the checksums file, certificate and signature
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.55.1/checksums.txt
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.55.1/checksums.txt.pem
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.55.1/checksums.txt.sig

# Verify the checksums file
cosign verify-blob checksums.txt \
  --certificate checksums.txt.pem \
  --signature checksums.txt.sig \
  --certificate-identity-regexp=https://github.com/carvel-dev \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com

Verify binary integrity

To verify the integrity of the downloaded binary, you can utilize the checksums file after having validated its signature.

# Verify the binary using the checksums file
sha256sum -c checksums.txt --ignore-missing
