Dear list members, I am not sure if this can be filed as a bug, but we are always eager to contribute, and we had just an issue with a production server and wanted that more experienced eyes had an opinion:
While creating a config, we have a server with the following configuration: server myserver1 supercool-dockercontainer:80 check resolvers docker_resolver resolve-prefer ipv4 Somehow we missed to put the "resolvers docker_resolver" configuration in the configuration file, so it was totally missing. We mean: the following was NOT in the config file: resolvers docker_resolver nameserver dns 127.0.0.11:53 However, by checking the configuration it was saying that the configuration was fine. This is the commands we were using (yes, we are sure this is the config file): /usr/local/sbin/haproxy -c -V /usr/local/etc/haproxy/haproxy.cfg First thing after running, haproxy sends an alert and dies: [ALERT] 218/105233 (1) : config : backend 'mybacken1', server 'myserver1': unable to find required resolvers 'docker_resolver' So obviously not having the resolver is an error that kills haproxy. However, it was not found with a configuration check. Then the question: -Was it the right way of checking the configuration? Missing some parameter? -If it was the right check, should it not be found by the configuration checker command?--> So we found a small little bug?;-). Thanks and have a nice day, Marcos Moreno.
