TFS™ Admin

When you select Settings on your TFS™ on Sawtooth deployment you are presented with this screen:

There are five tabs each of which is described in detail below.

TFS™ CLI

This tab provides you with the docker command you can use to spin up a TFS™ client that lets you interact with your deployment using the TFS™ CLI.

Warning

Note that the docker command works correctly only if you connect to Sextant via a load balancer otherwise the TFS_URL is malformed.

TFS™ Keys

This tab lets you create TFS™ keys for use when creating encrypted TFS™ volumes:

Important

You need to save the key locally as this is generated by Sextant but not retained by it.

TFS™ Volumes

This tab lets you create TFS™ volumes. Here we are creating vol001 and encrypting it using key001:

Having encrypted this volume we will need the key we saved earlier to read from or write to it but it is now listed:

This tab also lets us interact with the volumes. We can either View Snapshots, Create a Snapshot or Edit each volume using the three icons.

Clicking Edit lets you change the name of a volume:

Clicking Create a Snapshot switches the context to the TFS™ Snapshots pane and lets you create a snapshot of your volume.

TFS™ Snapshots

Here we are creating a second snapshot snap002 for vol001:

Which now appears in the snapshot list:

TFS™ Explorer

Before taking a closer look at the explorer, let's run a TFS™ CLI session using our docker command to spin up a tfs-client container:

[email protected]:/$ tfs-cli volume list
  VOLUME NAME               VOLUME UUID                COMPRESSION   ENCRYPTION
  vol002        caa56fc3-2206-4d52-8c7e-81b600bab5bf   NONE          NONE
  vol001        102f91d4-aeaa-4e40-b60b-f036f2844790   LZ4           AES_GCM
[email protected]:/$ ls /mnt/tfs
[email protected]:/$ tfs-fuse -v vol002 -m /mnt/tfs
[email protected]:/$ cd /mnt/tfs
[email protected]:/mnt/tfs$ ls
[email protected]:/mnt/tfs$ echo "hello world" > hello-world.txt
[email protected]78df5774:/mnt/tfs$ cat hello-world.txt
hello world
[email protected]:/mnt/tfs$ ls
hello-world.txt
[email protected]:/mnt/tfs$

The explorer lets you drill down on individual volumes such as vol002 and, as you can see, this lists the file hello-world.txt created in that session:

At this point you can Download, Open or request Info on this file. Opening it shows that the content mirrors the CLI session above:

Requesting its information provides you with the following readout:

Next we create (not shown) a snapshot snap001 for vol002 which is reflected in the explorer:

Next we return to our TFS™ CLI session where we can list the snapshot then create a second file descartes.txt:

[email protected]:/mnt/tfs$ tfs-cli volume snapshot list vol002
  SNAPSHOT NAME
  snap001
[email protected]:/mnt/tfs$ echo "I think therefore I am" > descartes.txt
[email protected]:/mnt/tfs$ cat descartes.txt
I think therefore I am
[email protected]:/mnt/tfs$
[email protected]:/mnt/tfs$ ls
descartes.txt  hello-world.txt

Returning to the explorer and looking at latest we can see the new file:

Note

The snapshots are stored in a hidden read-only directory .snapshots as you can see if you switch back to the TFS™ CLI session:

[email protected]:/mnt/tfs$ ls -ltr
total 0
-rw-r--r-- 1 user user 12 Dec  7 21:44 hello-world.txt
-rw-r--r-- 1 user user 23 Dec  7 22:22 descartes.txt
[email protected]:/mnt/tfs$ ls -ltr .snapshots/
total 0
dr--r--r-- 1 root root 0 Dec  7 21:07 snap001
[email protected]:/mnt/tfs$ ls -ltr .snapshots/snap001/
total 0
-rw-r--r-- 1 user user 12 Dec  7 21:44 hello-world.txt
[email protected]:/mnt/tfs$

Issues

SXT-867 TFS™ Explorer doesn't support encrypted volumes at present.
