[英]docker swarm - etcd cluster is unavailable or misconfigured
I'm trying to get started with docker swarm using etcd for the discovery backend . 我正在尝试使用etcd作为发现后端使用docker swarm。 My etcd server is at etcd.programster.org (10.1.0.44) whilst my docker node is at swarm1.programster.org (10.1.0.47).
我的etcd服务器位于etcd.programster.org(10.1.0.44),而我的Docker节点位于swarm1.programster.org(10.1.0.47)。 All machines are running on Virtualbox instances on my local network (10.1.0.x).
所有计算机都在本地网络(10.1.0.x)的Virtualbox实例上运行。
I manage to get my etcd server running with the following: 我设法让我的etcd服务器运行以下命令:
MY_IP="10.1.0.44"
./etcd \
-name infra0 \
-initial-advertise-peer-urls http://$MY_IP:2380 \
-listen-peer-urls="http://0.0.0.0:2380,http://0.0.0.0:7001" \
-listen-client-urls="http://0.0.0.0:2379,http://0.0.0.0:4001" \
-advertise-client-urls="http://$MY_IP:2379" \
-initial-cluster-token etcd-cluster-1 \
-initial-cluster infra0=http://$MY_IP:2380 \
-initial-cluster-state new
I can set and retrieve key values from swarm1.programster.org just fine with curl and etcd. 我可以使用curl和etcd从swarm1.programster.org设置和检索键值。
# setting key with etcdctl
./etcdctl --peers http://etcd.programster.org:4001 set etc://etcd.programster.org/mykey "test"
# setting key with curl
curl -L \
http://etcd.programster.org:4001/v2/keys/mykey \
-XPUT -d value="test"
# retrieving key with etcdctl
./etcdctl --peers http://etcd.programster.org:4001 get etc://etcd.programster.org/mykey
# retrieving key with curl
curl -L http://etcd.programster.org:4001/v2/keys/mykey
However, whenever I run a swarm based command such as: 但是,每当我运行基于群体的命令,例如:
docker run swarm list etcd://10.1.0.44/
or 要么
docker run swarm join --advertise=10.1.0.47:2375 etcd://10.1.0.44/
I always get the following error message: 我总是收到以下错误消息:
[timestamp] client: etcd cluster is unavailable or misconfigured
Have I configured my etcd server incorrectly or perhaps there is a networking configuration that I need to perform on the docker node first? 我的etcd服务器配置是否错误,或者是否需要首先在docker节点上执行网络配置? I have not performed any TLS authentication yet for simplicity but perhaps swarm will not work without this?
为了简单起见,我还没有执行任何TLS身份验证,但是如果没有此功能,可能无法群存?
Try including the port number like this: 尝试包括以下端口号:
docker run swarm join --advertise=10.1.0.47:2375 etcd://10.1.0.44:2379/swarm
I had the same issue and I assumed docker would intelligently infer the port number from "etcd://" - I was wrong. 我有同样的问题,我认为码头工人会智能地从“ etcd://”推断端口号-我错了。
