Some oddities:

• I can't find a replacement for test-joyent-ubuntu1804_docker-x64-1 in the table in Replacing machines from Joyent data center #2552. It also looks like all the hosts in https://ci.nodejs.org/search/?q=test-joyent that are containers (i.e. have the word "container" in their node names) are offline. Removed in this PR.
• It looks like test-joyent-ubuntu1604_arm_cross-x64-1 and release-joyent-ubuntu1604_arm_cross-x64-1 were removed from the inventory in https://github.com/nodejs/build/pull/2290/files#diff-6faf346b88ef5cbd5f6733c35ef37f0884f3fcc946a55c5b811843b652421f6d and possibly did not need to be migrated as we now cross compile in docker containers. The build history for https://ci.nodejs.org/computer/test-joyent-ubuntu1604_arm_cross-x64-1/builds is empty (i.e. no recent builds).
• infra-joyent-debian10-x64-1/grafana (from the table) doesn't appear to match anything in the inventory. Added in this PR.

infra-joyent-debian10-x64-1/grafana (from the table) doesn't appear to match anything in the inventory.

It was never added to inventory; perhaps add it as part of the list?

In terms of test-joyent-ubuntu1604_arm_cross-x64-1 and release-joyent-ubuntu1604_arm_cross-x64-1 I noticed that after the fact. I think we should just confirm with @rvagg and then spin those down.

For test-joyent-ubuntu1804_docker-x64-1 we may have missed that since the machine do not show up in the CI (instead the container ones do. Luckily we have a number of equivalent machines so nothing is blocked but we might have lower capacity than we want for the docker based testing. At this point I think we should look to add an additional docker host on one of the other infra's versus trying to bring that one back.

LGTM

I've removed test-joyent-ubuntu1804_docker-x64-1 from the inventory -- the old host is gone and we don't currently have a new one. I'll open a separate issue(s) to track removing the associated containers from Jenkins (we still have the equivalents at SoftLayer and DigitalOcean) and whether we want to replace it.
