OS Version/build: macOS High Sierra 10.3.3
App version: Docker for Mac Version 17.12.0-ce-mac49 (21995)
Steps to reproduce:
1. Add the relevant internal root certificate to the System keychain:
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/Downloads/My_Internal_Root_CA_1.pem
2. Have a Dockerfile with the following directives:
FROM jenkins/jenkins:lts RUN curl -v https://<my domain requiring internal root certificate>.com
3. Run docker build
Building from the Dockerfile fails with curl: (60) SSL certificate problem: self signed certificate in certificate chain.
From the documentation, it appears that the certificate should be available to the container after adding it to the Mac’s System keychain but that is not working. Additionally, I do not see the certificate in the /etc/ssl/certs/ folder on the container.
