error when starting traefik

[zaibon]

I was trying to deploy a web gateway combination of etcd, coredns and traefik. Everything works ok until I tried to start the traefik service and got this error:

Here is my deploy script:

    def deploy(self, node_id):
        robot = j.clients.zrobot.get_by_id(node_id)

        logger.info("install zerotier client")
        zt = robot.services.find_or_create('zerotier_client', 'zt', data={'token': self._zt_token})

        tasks = []
        logger.info("install etcd")
        etcd = robot.services.find_or_create('etcd', 'etcd_'+self.name, data={
            'nics': [{'name': 'zerotier', 'type': 'zerotier', 'ztClient': 'zt', 'id': self._zt_id}],
            'token': 'cluster_%s' % self.name,
        })

        tasks.append(etcd.schedule_action("install").wait(die=True))
        tasks.append(etcd.schedule_action("start").wait(die=True))

        logger.info("install coredns")
        coredns = robot.services.find_or_create('coredns', 'coredns_'+self.name, data={
            'nics': [{'name': 'zerotier', 'type': 'zerotier', 'ztClient': 'zt', 'id': self._zt_id}],
            'etcd': etcd.name
        })

        tasks.append(coredns.schedule_action("install"))
        tasks.append(coredns.schedule_action("start"))

        logger.info("install traefik")
        traefik = robot.services.find_or_create('traefik', 'traefik_'+self.name, data={
            'nics': [{'name': 'zerotier', 'type': 'zerotier', 'ztClient': 'zt', 'id': self._zt_id}],
            'etcd': etcd.name
        })

        tasks.append(traefik.schedule_action("install"))
        tasks.append(traefik.schedule_action("start"))
        return tasks

@zaibon now i think we should close this issue ? last commit: https://github.com/threefoldtech/jumpscale_lib/commit/95df09864991e9321d569255389cdeb8f9257e87

[zaibon]

let's wait to confirm our fixes indeed solve it completely
