Marton Elek created HDDS-2895: --------------------------------- Summary: Generate only the required keytabs for docker based secure tests Key: HDDS-2895 URL: https://issues.apache.org/jira/browse/HDDS-2895 Project: Hadoop Distributed Data Store Issue Type: Improvement Reporter: Marton Elek
We have acceptance tests with the help of docker/docker-compose where we generate the keytab files on the fly with the help of a lightweight (unsecure) REST endpoint. But this generation can be very slow especially when the DNS is slow. When I start a VPN the secure cluster can't be started in the 90 sec period. (>100 keytabs are generated and one keytab generation is ~5 sec). The solutions is to generate only the *required* keystabs in each of the containers. Instead of request all the possible keytabs in the *generic* docker-config: {code:java} KERBEROS_KEYTABS=dn om scm HTTP testuser testuser2 s3g {code} We can defined the required keytabs per service (in docker-compose.yaml) {code:java} environment: KERBEROS_KEYTABS=scm HTTP{code} With this approach ~20 keytab file will be generated instead of >100 and the secure tests will be significant faster. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: ozone-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: ozone-issues-h...@hadoop.apache.org
