I am using the dokcer version - latest from https://releases.mattermost.com/5.27.0/mattermost-5.27.0-linux-amd64.tar.gz?src=docker - I have this in my Dockerfile settings and I build my Server using the Settings posted in the github.
FROM alpine:3.12
# Some ENV variables
ENV PATH="/mattermost/bin:${PATH}"
ARG PUID=2000
ARG PGID=2000
ARG edition=team
ARG MM_PACKAGE="https://releases.mattermost.com/5.27.0/mattermost-5.27.0-linux-amd64.tar.gz?src=docker"
# Install some needed packages

# Get Mattermost
RUN mkdir -p /mattermost/data /mattermost/plugins /mattermost/client/plugins \
&& if [ ! -z "$MM_PACKAGE" ]; then curl $MM_PACKAGE | tar -xvz ; \
else echo "please set the MM_PACKAGE" ; fi \
&& addgroup -g ${PGID} mattermost \
&& adduser -D -u ${PUID} -G mattermost -h /mattermost -D mattermost \
&& chown -R mattermost:mattermost /mattermost /mattermost/plugins /mattermost/client/plugins
The above is the content of my Dockerfile - as I used the same as the one in the github.
Thanks
