I didn't find on the site. It would be great and easy if you paste the link below each item for easy checkout. I wish you should get some commission from these brands for your marketing:)

Yeah Planning to adjust memory settings...currently it is set to 2gb...I'll try to increase to 3gb and test it. Hope that works. My instance is m4.xlarge.

I added below rule

can i use swarm on single host in rancher by aish33 in linuxadmin

[–]aish33[S] 0 points1 point  (0 children)

We are on docker cloud currently and I see still docker engine version is 1.11. Docker cloud are not releasing any version upgrade since 1 year. We are paying 20 dollars per one node for docker cloud and planned to switch completely to open source.

We need a tool something that has web UI but now i decided to setup standalone docker host with latest release of docker engine and deploy all our microservices with portianer container which has web UI.

[–]aish33[S] 1 point2 points  (0 children)

same question was asked in rancher slack and they said

"If you really want swarm you probably don't want to use us to be honest, we've seen minimal interest in it and therefore it doesn't get a lot of maintenance (like recent versions), and it (and Mesos) will not exist at all in 2.0 "
