> {{ENV}} directive in the various Docker files is using the legacy syntax,
> i.e.:
> {noformat}
> ENV <key> <value>{noformat}
> This produces warnings on newer Docker Engine.
> {noformat}
> 4 warnings found (use docker --debug to expand):
> - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV
> key value" format (line 28)
> - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV
> key value" format (line 29)
> - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV
> key value" format (line 26)
> - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV
> key value" format (line 27)
> {noformat}
> The proper syntax is:
> {noformat}
> ENV <key>=<value>{noformat}
> See the [Docker
> documentation|https://docs.docker.com/reference/dockerfile/#env] for more
> details.
> Also, the {{chown}} syntax is using {{.}} instead of {{:}} which produces
> this warning:
> {noformat}
> #9 [5/7] RUN mkdir /var/lib/artemis-instance && chown -R artemis.artemis
> /var/lib/artemis-instance
> #9 0.148 chown: warning: '.' should be ':': ‘artemis.artemis’
> {noformat}
