Here you’ll learn to setup TUS an open source resumable file upload server to process uploads for Galaxy. We use an external process here to offload the main Galaxy processes for more important work and not impact the entire system during periods of heavy uploading.

TUS and Galaxy
To allow your user to upload via TUS, you will need to:
- configure Galaxy to know where the files are uploaded.
- install TUSd
- configure Nginx to proxy TUSd
Installing and Configuring

If you haven’t worked with diffs before, this can be something quite new or different.
If we have two files, let’s say a grocery list, in two files. We’ll call them ‘a’ and ‘b’.

There are a couple different formats to diffs, one is the ‘unified diff’

🥑This is basically what you see in the training materials which gives you a lot of context about the changes:
--- old
is the ‘old’ file in our view+++ new
is the ‘new’ file- @@ these lines tell us where the change occurs and how many lines are added or removed.
- Lines starting with a - are removed from our ‘new’ file
- Lines with a + have been added.
So when you go to apply these diffs to your files in the training:
- Ignore the header
- Remove lines starting with - from your file
- Add lines starting with + to your file
The other lines (🍊/🍋 and 🥑) above just provide “context”, they help you know where a change belongs in a file, but should not be edited when you’re making the above change. Given the above diff, you would find a line with a 🍒, and replace it with a 🍍
Added & Removed Lines
Removals are very easy to spot, we just have removed lines

We proxy the service next to Galaxy. As it resides “under” the Galaxy path, clients will send cookies and authentication headers to TUS, which it can use to process the uploads before telling Galaxy when they’re done.

Run the playbook
Input: Bashansible-playbook galaxy.yml
Congratulations, you’ve set up TUS for Galaxy.
Check it works
Hands-on: Check that it works.
SSH into your machine
Check the active status of tusd by
systemctl status galaxy-tusd
.Upload a small file! (Pasted text will not pass via TUS)
Check the directory
/data/tus/
has been created and it’s contentsInput: Bashsudo tree /data/tus/
You’ll see files in that directory, a file that’s been uploaded and an ‘info’ file which contains metadata about the upload.
1.sh
Hands-on: Time to git commitIt’s time to commit your work! Check the status with
git status
Add your changed files with
git add ... # any files you see that are changed
And then commit it!
git commit -m 'Finished Performant Uploads with TUS'
Comment: Got lost along the way?If you missed any steps, you can compare against the reference files, or see what changed since the previous tutorial.
If you’re using
git
to track your progress, remember to add your changes and commit with a good commit message!
