[couchdb-docker] 01/01: 3.1.0-ubi: add UBI 8 container definition
This is an automated email from the ASF dual-hosted git repository.
willholley pushed a commit to branch ubi-3.1.0
in repository https://gitbox.apache.org/repos/asf/couchdb-docker.git
commit b6843be46196b339899954589f9cde300eb5ec49
Author: Will Holley <wi...@uk.ibm.com>
AuthorDate: Mon May 11 10:19:07 2020 +0100
3.1.0-ubi: add UBI 8 container definition
Adds a Dockerfile and supporting files to run CouchDB 3.1.0
on UBI 8. This is largely a clone of the 2.3.1-UBI assets, updated
where required, to support CouchDB 3.x.
Specifically, the default entrypoint now requires an admin username
and password to be supplied.
Since it installs the community-maintained rpm, the container
uses SpiderMonkey 60 as the JavaScript runtime for CouchDB.
