Docker images that are part of the TRUE Connector are signed using cosign. In releases section, you can find appropriate version of cosign executable, appropriate of the target OS.
Signed images starts with following versions:
rdlabengpa/ids_execution_core_container:v1.14.8\
rdlabengpa/ids_be_data_app:v0.3.8\
rdlabengpa/ids_uc_data_app_platoon:v1.7.9\
rdlabengpa/ids_uc_data_app_platoon_pip:v1.0.0\
Once images are downloaded, you can verify the signature by executing following command, (trueconn.pub file can be found in the ecc_cert folder) and response should be like following
NOTE: Versions of cosing greater than 2.0.x will require to provide additional flag --insecure-ignore-tlog, to avoid message like following:
Error: no matching signatures:
signature not found in transparency log
main.go:69: error during command execution: no matching signatures:
signature not found in transparency log
cosign verify --insecure-ignore-tlog --key trueconn.pub rdlabengpa/ids_execution_core_container:v1.14.8
WARNING: Skipping tlog verification is an insecure practice that lacks of transparency and auditability verification for the signature.
