I didn't trace back what caused this to start happening, but I was able to work around it by installing bash as part of the dockergen Dockerfile:
RUN apk add bash bash-doc bash-completion
So this is what my dockerfile looks like now:
FROM jwilder/docker-gen COPY haproxy.tmpl /etc/docker-gen/templates/haproxy.tmpl COPY run.sh /run.sh RUN chmod +x /run.sh RUN apk add bash bash-doc bash-completion ENTRYPOINT ["/bin/bash", "-c"] CMD ["/run.sh"]
The even better thing to do would be to remove the need for run.sh outright and move that command to your Dockerfile directly, as so:
CMD ["sh", "-c", "/usr/local/bin/docker-gen -notify-sighup ${PROJECT}_${SERVICE}_1 -watch /etc/docker-gen/templates/haproxy.tmpl /usr/local/etc/haproxy/haproxy.cfg"]
So the full file now looks like this:
FROM jwilder/docker-gen
COPY haproxy.tmpl /etc/docker-gen/templates/haproxy.tmpl
CMD ["sh", "-c", "/usr/local/bin/docker-gen -notify-sighup ${PROJECT}_${SERVICE}_1 -watch /etc/docker-gen/templates/haproxy.tmpl /usr/local/etc/haproxy/haproxy.cfg"]
@dotLou Is this working? I had this in mind initially, but ended with obscure errors.
I think it's an issue if you don't specify "sh", "-c"
but otherwise seems to work for me.
I think I take that back.. I need to further investigate, it's not working anymore :(
Hi, tried to use the example but fails so start.
➜ auto-haproxy git:(master) docker-compose up -d autohaproxy_app_1 is up-to-date Starting autohaproxy_haproxy-gen_1

docker-compose returned -1
Think docker has change how volumes are created and the naming now uses catalog name.
