@lumir-mrkva - haven't made the move to traefik 2.0 yet, scheduled to look into that in our lab cluster in 2-3 weeks. Things just got stable

also - I see the 'View Logs' on services, is there a way to run a command - like bash to get into a running container?

Pavol Noha

@nohaapav

@mhsutton_gitlab Hi Mike, you can't exec into container via Swarmpit at the moment.

Mike

@mhsutton_gitlab

perhaps a little off topic but... one postgres per app database or one shared postgres container with multiple app databases?

shared container pros: easier to manage, backup, replicate. Cons: single point of failure (all apps down if pg container goes down)
per app postgres pros - resilience/app isolation; Cons: different versions, more stuff to maintain, replicate

How do you decide?

Mike Holloway

@mh720

@mhsutton_gitlab scaling is possibly the concern for pointing all your apps at the same db instance. If the load from your multiple apps is easily served by a single postgres instance, this might be desired due to the management pros you shared. As your load grows over time, you could always spin up another db instance and migrate data for one of your busy DBs into it and re-point apps.

Mike

@mhsutton_gitlab

@mh720 yeah - really good point, unfortunately instance scaling is not an option yet (because persisted volumes are too slow) and actually having more replica nodes makes no difference to capacity. I think what you outline is the only way to share the load. Which is not a bad option, things will have to have gotten seriously busy though. The replica stuff already provides replication on servers in a different geo-zone

@mh720 thanks for the response

Hi Guys, i am new to Swarmpit. Currently we have running swarmpit for my production based docker swarm.

version is 1.5. How to upgrade the version of Swarmpit ?

Pavol Noha

@nohaapav

Check the compose for given version and update yours accordingly ..

E.g. to upgrade to 1.7 This one:
https://github.com/swarmpit/swarmpit/blob/1.7/docker-compose.yml

Of course update just deltas -> versions, and things that were introduced since 1.5

SamyOteroGlez

@SamyOteroGlez

Would it be possible to define a host volume suing swarmpit?

volumes:
      - ./my_volume:/opt/my_volume/data

or it is just limited to anonymous and named volumes?

lumir-mrkva

@lumir-mrkva

@SamyOteroGlez this should work fine by using stackfile - we just give this file to docker to parse it and process it, but if you want to bind host location by using create service workflow in swarmpit, you have to chose type "bind" instead of (named) volume

@lumir-mrkva Thanks!

Hey guys, I was looking for a Rancher 1.6 alternative to use with https://appwrite.io and Rancher 2.0 seems to have lost the simplicity first approach by putting all the cards on Kubernetes (which seems to me like an overkill for most small to medium companies or apps). I tried Swarmpit over the last few days and really liked how simple everything was. Is swarmpit production ready? is there any public roadmap available?

Pavol Noha

@nohaapav

@eldadfux Hi Eldad. Yes, we run Swarmpit in PROD for our internal infrastructure, fintech and so on. As you mentioned: Swarmpit/Swarm is aimed for small/medium companies and startups tired of complex solutions in the era of rapid development.
You can find ROADMAP here: https://github.com/swarmpit/swarmpit/blob/master/ROADMAP.md
We'll update info regarding 1.9 RELEASE soon as well as landing page.

Eldad A. Fux

@eldadfux

@nohaapav thank you so much, this project look awesome! I really love how everything is so simple and how you are avoiding from adding new concepts and bigger learning curves. I think you might be able to save me from migrating to kubernetes!

@dennismi

hey guys, a quick question, how do i authenticate myself to the API?

Dennis Micheelsen

@dennismi

hmm.. an post to /login with authorization: basic <base64 username:password> ... but according to jwt.io, the bearer token does not have a valid signature, but it still works...

Pavol Noha

@nohaapav

well you need a secret in order to validate signature ..

this one is stored in swarmpit DB

To use swarmpit API go to settings section and generate API token.

@radekerben

Hi, swarmpit dont show disk usage on volume, if i used local-persist plugin. Why? Thnank you for help

Dennis Micheelsen

@dennismi

@nohaapav got it...

@nohaapav

@dennismi there is issue with material update .. the fab button component is missing in new release .. it will be fixed with following issue: swarmpit/swarmpit#415

Dennis Micheelsen

@dennismi

@nohaapav ok, got it... will wait then :)

@capriciousduck

I get target error while building my own image. Anyone know about that ?

I am using the git repo dockerfile

@millsoft

hi everyone. How can I uninstall swarmpit (I installed it using the docker command provided on the website)? I am trying to stop and remove the containers but they are being restarted.. I also changed the restartpolicy to no but it doesn't work... :/

nevermind, found an answer on some website:

docker stack rm swarmpit

Matthias Baldi

@matthiasbaldi

around the subject of the takeover of Docker Enterprise by Mirantis. Because of issues like this (docker/swarm#2965) I have some concerns about the future from Docker Swarm and with it also Swarmpit. Both products are awesome and helped me to implement an easy platform.
So how do you think from the "Swarmpit" point of view about the future?
Do you have some further information?

Pavol Noha

@nohaapav

@matthiasbaldi Docker Swarm is OS project so even if the Docker stops development, support can live within the community. We choose this orchestrator because it's easy to learn and nearly all features can be understood by average developer in a full day class. We believe that in the ERA of rapid development, prototyping, startups such orchestrator is essential. It's still second largest on market and Docker will be stupid to shut it down entirely. And if they do so, new one following the same goal (simplicity) will find the way to shine. We run our entire infrastructure (multiple customers) on Swarm and if there is any transition regarding orchestrator we're going to support it as well.

Matthias Baldi

@matthiasbaldi

@nohaapav I completely agree to that.
Thanks for your answer. Then let's see what the future will bring to Docker Swarm. :thumbsup:

Eric Barber

@ericbarber01_twitter

new to swarmpit - how do get the node names to show correctly? Also I am unable to add my registry by hostname only ip works?

lumir-mrkva

@lumir-mrkva

@ericbarber01_twitter seems like some sort of dns configuration issue, there is nothing you can do about it in swarmpit itself, nodes have to be configured properly

Eric Barber

@ericbarber01_twitter

any idea how to change the time zone in swarmpit? I passed -e TZ='America/New_York' but no luck. Dashboard still shows UTC.

Pavol Noha

@nohaapav

@ericbarber01_twitter not supported yet. See swarmpit/swarmpit#400

@francis2211

I am playing with Swarmpit and I was wondering how can I add a new node to swarmpit?

Currently, I have 3 nodes running, and I just added another one how can I start the agent on that node

Pavol Noha

@nohaapav

You have to connect node via swarm api .. swarmpit has not such feature yet. To start agent just deploy agent service globally .. see swarmpit stack .. @francis2211

Matthias Baldi

@matthiasbaldi

@francis2211 as Pavel explained: You only have to add the node to your swarm cluster, then Swarmpit should automatically deploy the agent.
As example for a global agent service:

...
services:
 agent:
   image: swarmpit/agent:latest
   volumes:
     - /var/run/docker.sock:/var/run/docker.sock:ro
   logging:
     options:
       max-size: 5M
   deploy:
     mode: global
     resources:
       limits:
         cpus: '0.10'
         memory: 64M
       reservations:
         cpus: '0.05'
         memory: 32M

Hi All,

Are there any memory/resource leak issues known for AWS ECR registry support and/or autoredeploy? It might be a coincidence, but since I added a service in a private AWS ECR registry with autoredeploy I've had memory issues with the swarmpit container. I've just restarted the swarmpit container today (actually, had to restart manager node as it also used up all system threads, so I couldn't ssh in) and am monitoring for a few hours and then will be turning off the autoredeploy; but was just curious if others had seen this?

I Stevenson

@irstevenson

hmmm, initial indications after turning off the autodeploy one and a half hours ago is that memory usage on the node has stablised again. Indeed the memory usage looks to be slowly dropping (to potentially free resources from the first four hours but at a much slower rate).

And to show a longer term graph capturing the first restart and then subsequent repeat event:
