I am trying to install Consul with my private PKI.
It seems that consul does not like my server cert despite it works fine with Tomcat, LDAP server, etc.
This is the relevant config:
"tls": {
"defaults": {
"key_file": "/tmp/consul.hello.com.plain-key",
"cert_file": "/tmp/consul.hello.com.crt",
"ca_file": "/tmp/ca.crt",
"verify_incoming": true,
"verify_outgoing": true,
"verify_server_hostname": false
}
}
And this is the error I get:
agent.server.rpc: failed to read byte: conn=from=127.0.0.1:53133 error="tls: failed to verify certificate: x509: certificate specifies an incompatible key usage"
Unfortunately there is nothing concrate in the log about the real reason.
CA cert:
$ openssl x509 -text -noout -in /tmp/ca.crt
Certificate:
