x509: certificate signed by unknown authority¶

After adding the tls.crt to the path /etc/ssl/certs or /usr/local/share/ca-certificates and run update-ca-certificates. The command curl -kv https://my.example.com shows SSL certificate verify ok but docker build shows x509: certificate signed by unknown authority.

After updating OS certificates, we typically need to restart the docker service to get it to detect that change. This is usually done with:

sudo systemctl restart docker

sudo service docker restart
