docker swarm init --advertise-addr=192.168.56.102. However, when I try to join the swarm on my other nodes I get an error claiming Error response from daemon: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 192.168.56.102:2377: connect: no route to host", which is funny because I can ping and ssh to the supposedly unavailable destination with no issues. Anyone got any ideas?
Hello everyone, I am trying to dockerize my production app(based on LAMP stack). Currenty, I am using plain git to manage code. I am trying to figure out
- how docker plays with git. 2. Do I need to use Jenkins to always create new docker with the updated git code.
Hi I trying to implement sticky session on dockers-swarm with traefik, but I could not achieve session persistence over two replicas on same machine.
In my docker-compose.yml, I have added labels for traefik and added the loadbalancer as well. Am I missing anything?
Or is there a better way to maintain session persistence?
I have a PHP backend and taking about maintaining same PHP session variables across replicas

{{.Service.Name}} the service gets created, however the hostname shows literally as {{.Node.Hostname}}-{{.Node.ID}}

Hi All,
I have an ubuntu and win10 machine and try to join them using swarm
So on win 10 i did a docker swarm inint and it gave me
docker swarm join --token SWMTKN-1-2x0d8gcwdajbjt78xtgnfdgrlggd2yp9sh6t3klcx48bszl7nk-99on3a92ej4pdhgbglfmdychy 192.168.65.3:2377
i copied this to ubuntu machine and the response was
Error response from daemon: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 192.168.0.8:2377: connect: connection refused"
faizal@faizal-K42JA:~/hypledger$ docker swarm join --token SWMTKN-1-5m96ou268r2csm89faroxa4313crw484px8kzyvkthq9ggdixc-8xqlzsnp1w41khm3i84ek5sl8 192.168.0.8:2377
i coudnt do a telnet even from my win10 mchine or even ping it.
How to make win10 as manager and ubuntu as worked using docker swarm
docker swarm init command provided you with the command you have to run on the swarm nodes to join the swarm cluster. In your sample it was docker swarm join --token SWMTKN-1-2x0d8gcwdajbjt78xtgnfdgrlggd2yp9sh6t3klcx48bszl7nk-99on3a92ej4pdhgbglfmdychy 192.168.65.3:2377. But I see different token and IP was used later in your sample. Could it be a problem there?
I have docker-compose file, In which i have defined few services, some of them directly taking image from docker hub and some i am creating using build.So when I am deploying it using docker swarm , so those images that are available in docker hub , is successfully started in my other nodes but , those images that i created, is running only my manager node because it's a available on manager node, so can any one help how to distrubute or run my other images to the other nodes as well usig docker swarm, Without pushing it to create own repo
Hi everyone,
I have a very simple python script, not a web app, it runs based on some arguments and returns something, I run it with “docker run —rm -it my_image:v1 python mydir/app.py”, I see that host folder that I added as a volume can’t be find in the container.
To test it, I created a python hello world flask app and run it with docker-compose up, in this case volumes are working fine, changes in the host machine is reflected to the running container. But this doesn’t look a good solution to me.
Is there a way to run the app with “docker run —rm -it my_image:v1 python mydir/app.py” and use volumes so if I change a file in the host, python mydir/app.py will consume the right content.
I worked hours on that, tried adding volume on the fly with -v parameter, used docker compose, only Dockerfile with volume description etc.
I’ll be appreciated if at least you can share some docs, blogs or ideas.
Regards!
volume mounts over bind mounts. Docker Service Volumes
node-1 with a volume mount, and if node-1 goes down the serviceis migrated to
node-2 the service will create a new volume on node-2 that will not have the same data as the local volume created on node-1.
