How to Import CA Certificate chain in Gitlab-ce 8.14.6

@axil, @warren.postma,

Hello Team,

Please let me know how can we import CA certificates in Gitlab. We have imported certificates in Gitlab But still we are seeing verify error when we run openssl s_client command. Let me know the exact steps how to import certificates.
openssl s_client -connect :443
CONNECTED(00000003)
depth=2 C = US, O = International Business Machines Corporation, CN = IBM Internal Root CA
verify error:num=19:self signed certificate in certificate chain

verify return:0

Start Time: 1525251146
Timeout : 300 (sec)
Verify return code: 19 (self signed certificate in certificate chain)

If we want to import Jira certificates to Gitlab’s trust store, where we need to import as gitlab doesn’t have any keystore. We are trying to integrate Gitlab-ce and Jira. But it is not working due to certificate issue.

Thanks,
Prashanthi.
