-----------------------------
Summary: Enabling SSL causes fetcher fail to fetch from HTTPS
sites.
Key: MESOS-5863
URL: https://issues.apache.org/jira/browse/MESOS-5863
Project: Mesos
Issue Type: Bug
Affects Versions: 0.28.2, 0.27.3, 1.0.0
Reporter: Jie Yu
This is because curl (which fetcher replies on) also relies on some of the
environment variables used by libprocess SSL support. For instance,
`SSL_CERT_FILE`. For instance, if the operator sets `SSL_CERT_FILE` env var for
Mesos agent, the fetcher will inherit this env var and cause curl to fail:

[centos@ip-10-10-0-205 ~]$
SSL_CERT_FILE=/run/dcos/pki/tls/certs/mesos-slave.crt curl
https://registry-1.docker.io:443/v2/library/alpine/manifests/latest
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
