# Download the binary
curl -LO https://github.com/carvel-dev/imgpkg/releases/download/v0.47.2/imgpkg-linux-amd64

# Move the binary in to your PATH
mv imgpkg-linux-amd64 /usr/local/bin/imgpkg

# Make the binary executable
chmod +x /usr/local/bin/imgpkg

Verify checksums file signature

Install cosign on your system https://docs.sigstore.dev/system_config/installation/

The checksums file provided within the artifacts attached to this release is signed using Cosign with GitHub OIDC. 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/imgpkg/releases/download/v0.47.2/checksums.txt
curl -LO https://github.com/carvel-dev/imgpkg/releases/download/v0.47.2/checksums.txt.pem
curl -LO https://github.com/carvel-dev/imgpkg/releases/download/v0.47.2/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
