What Centos AMI do you use on AWS?
What size of machine do we need for a typical DSCI 100 course (keeping in mind we want to use EFS, not EBS)?
Would kubernetes help solve our loading/logging on problems?
What security groups do you suggest using for the instances that host the JupyterHubs (we set up TLJH with the default VPC security group, but now are using SSH, HTTP & HTTPS)
why inventory-ad-hoc instead of hosts?
FIPPA compliant email address for bot

Action items:

existing hub is 16 CPUs & 64 GB, see screenshots for suggested starting place (so chose this as a starting place on AWS: General purpose | m5.4xlarge | 16 | 64 | EBS only | Yes | Up to 10 Gigabit | Yes)
blkid let's you know where the filesystems are (can give device arguments)

(note - last volume is for Docker ephemeral storage)

ttimbers commented 4 years ago

add ICMP as a security group
Might want to add a UBC VPN ssh restriction
to specify which private key private_key_file = ../keys/private_key.pem in inventory_ad_hoc OR add my public key to AWS (somehow) (latter is preferred or you will have to update to the public keys later if we use the former)

FIPPA compliant email address for bot

relay hosts, talk to The Ha for a stat email address to do this (just for sending email... ).

@ttimbers is this still an open issue?
