Persistent notebook

I have a persistent instance running.

I followed this blog post to get it set up.

I can connect to it via

ssh -i ~/dotfiles/sglyon-mbp.pem.txt ubuntu@ec2-54-201-41-126.us-west-2.compute.amazonaws.com

ipython notebook --profile=julia is running. I can connect to it from any browser by going to


new user

I made a new user here by following the ideas here

Mounting a volume

I mounted a volume to ~/storage (sudo mount /dev/xvdf /home/sglyon/storage), but didn’t have permission to do anything. To fix that I chowned it: sudo chown -R sglyon ~/storage


First step is to install the tools. This is a one time thing where I enter this command:

curl https://sdk.cloud.google.com | bash

Then follow the prompts and such until it is installed. I chose the directory ~/google-cloud-sdk

I didn’t have it alter my path for me, but I added the following line in my list where I set $PATH from within my ~/.zshenv:


Julia and GCE

I (partially) followed this blog post to get things started.

To create a new instance from the command line I need to run the following

gcloud compute --project "sgl-julia" instances create "instance-name" --zone "us-central1-b" --machine-type "n1-standard-1" --network "default" --maintenance-policy "MIGRATE" --scopes "https://www.googleapis.com/auth/devstorage.read_only" --image "https://www.googleapis.com/compute/v1/projects/sgl-julia/global/images/julia-src-deb-10212014" --no-boot-disk-auto-delete

where instance-name is replaced with the actual name of the instance I want to create.

I can then ssh into the new instance (after it is created) by running

gcloud compute --project "sgl-julia" ssh --zone "us-central1-b" "instance-name"

If I want to select a different type of instance, I would change the --machine-type parameter name. See this page for an explanation of the different types and prices.

To turn off (delete) my instance I would enter the following command:

gcloud compute --project "sgl-julia" instances delete "instance-1" --zone "us-central1-b"

If I also wanted to delete the corresponding persistent disk I would enter

gcloud compute --project "sgl-julia" disks delete "instance-1" --zone "us-central1-b"

Writing the package

I had to install this script in order for ssh to work. I did the following:

cd ~/Downloads
git clone https://github.com/markcarver/mac-ssh-askpass
cd mac-ssh-askpass
sudo ./INSTALL

The package also requires that gcloud and friends are installed.
