Show both size and actual size of files (#742 )

Right now we show only actual size of files on disk which excludes empty blocks of the recently introduced sparced format in #671. This makes impossible to get info about disk size that we just set via `tart set`. Here is an example of `tart list` output before the change: ``` Source Name Size State local sonoma-base 22 stopped local sonoma-vanilla 18 stopped local sonoma-xcode 67 stopped local ubuntu 1 stopped oci ghcr.io/cirruslabs/macos-sonoma-base:latest 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-base@sha256:16c1593bbaf787b20b3c0bc094c5b6baf71c937d22c2e4596da85ac55c92e6cc 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla:14.3 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla@sha256:23c4e853d48d00a4333346d66a32b2b5aad900cc0dc10e7ecb9dbe67b6f587f4 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode:latest 67 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode@sha256:d0cb8d01424a68b89e0f16f5371bf2152b2c115bd886341a6ba8da42121d1f41 67 stopped oci ghcr.io/cirruslabs/ubuntu:22.04 1 stopped oci ghcr.io/cirruslabs/ubuntu@sha256:037763feb7a15d6077edeb7a097738c34313637d16036764b4c196d28d8b429c 1 stopped ``` And here is the output after the change: ``` Source Name Disk Size State local sonoma-base 50 22 stopped local sonoma-vanilla 50 18 stopped local sonoma-xcode 90 67 stopped local ubuntu 20 1 stopped oci ghcr.io/cirruslabs/macos-sonoma-base:latest 50 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-base@sha256:16c1593bbaf787b20b3c0bc094c5b6baf71c937d22c2e4596da85ac55c92e6cc 50 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla:14.3 50 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla@sha256:23c4e853d48d00a4333346d66a32b2b5aad900cc0dc10e7ecb9dbe67b6f587f4 50 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode:latest 90 67 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode@sha256:d0cb8d01424a68b89e0f16f5371bf2152b2c115bd886341a6ba8da42121d1f41 90 67 stopped oci ghcr.io/cirruslabs/ubuntu:22.04 20 1 stopped oci ghcr.io/cirruslabs/ubuntu@sha256:037763feb7a15d6077edeb7a097738c34313637d16036764b4c196d28d8b429c 20 1 stopped ``` Additionally, `tart get` will print actual size with a 3 decimal point precision which will help to track growth in disk images for our templates. `tart get` before: ``` CPU Memory Disk Display State 4 8192 67 1024x768 stopped ``` `tart get` after: ``` CPU Memory Disk Size Display State 4 8192 90 67.333 1024x768 stopped ```

+# New dashboard with insights into performance of Cirrus Runners
+
+This month we are celebrating one year since launching Cirrus Runners — managed Apple Silicon infrastructure for your
+GitHub Actions. During the last 12 months we ran millions of workflows for our customers and now ready to share some insights
+into price performance of them for our customers.
+
+One of the key difference with Cirrus Runners is how they are getting billed for. Customers purchase Cirrus Runners via monthly subscription
+that costs $150 per each Cirrus Runner. Each runner can be used 24 hours a day 7 days a week to run GitHub Actions workflows
+for an organization. If there are more outstanding jobs than available runners then they are queued and executed as soon as
+there is a free runner. This is different from how GitHub-managed GitHub Actions are billed for — you pay for each minute of execution time.
+
+The benefit of a fixed price is that you can run as many jobs as you want without worrying about the cost. The downside is that
+you need to make sure that you are using your runners efficiently. This is where the new dashboard comes in handy.
+
+<!-- more -->
+
+But first, **let's see theoretically the lowest price per minute** of a Cirrus Runners. If you run 24 hours a day 7 days a week
+then you will get 43,200 minutes of execution time per month. This means that the price per minute is $0.0035 if your runners
+utilization is 100%. But even if your engineering teams is located in a single time zone and works 8 hours a day 5 days a week
+then you will get 9,600 minutes of execution time per month which comes down to $0.015 per-minute. This is still more than 10 times cheaper
+than recently announced Apple Silicon GitHub-manged runners that cost $0.16 per minute.
+
+Now lets take a look at the new Cirrus Runners dashboard of a real customers that run their workflows on Cirrus Runners
+and **practically pushing the price performance pretty close to the theoretical minimum**.
+
+![Cirrus Runners Dashboard](/blog/images/runners-price-performance-2.png)
+
+As you can see above Cirrus Runners Dashboard focuses on 4 core metrics:
+
+1. **Minutes Used** — overall amount of minutes that Cirrus Runners were executing jobs.
+2. **Workflow Runs** — absolute number of workflow runs that were executed on Cirrus Runners.
+3. **Queue Size** — number of jobs that were queued and waiting for a free Cirrus Runner.
+4. **Queue Time** — average time that jobs were waiting in the queue.
+
+In this particular example price performance of Cirrus Runners is $0.006 per minute which is 2 times more than the theoretical minimum
+and **26 times better than GitHub-managed Apple Silicon runners**. But this is a extreme example, looking at queue time and queue size
+we can see that the downside of such great price performance is that jobs are waiting in the queue on average around 5 minutes.
+
+Here is another example of Cirrus Runners Dashboard for a different customer that has a slightly higher price performance of $0.017 per minute
+but at the same time doesn't experience queue time at all. **Note that $0.017 is still 10 times cheaper than GitHub-managed Apple Silicon runners**.
+
+![Cirrus Runners Dashboard](/blog/images/runners-price-performance-3.png)
+
+## Conclusion
+
+Having a fixed price for Cirrus Runners is a great way to save money on your CI/CD infrastructure and just in general have predictable budged.
+But it requires keeping the balance between price per minute and queue time. Cirrus Runners Dashboard helps you to keep an eye on this balance
+and make sure that you are getting the most out of your Cirrus Runners.

+
+>Keychain failed to update item: User interaction is not allowed.
+
+This is because Tart uses [Keychain](https://en.wikipedia.org/wiki/Keychain_(software)) to store and retrieve OCI registry credentials by default, but Keychain is only automatically/semi-automatically unlocked in GUI sessions.
+
+To unlock the Keychain in an SSH session, run the following command, which will ask for your user's password:
+
+```shell
+security unlock-keychain
+```
+
+This command also supports the `-p` command-line argument that allows you to supply the password and unlock non-interactively, which is great for scripts.
+
+If that doesn't work for you for some reason, you can pass the credentials via the environment variables, see [Registry Authorization](integrations/vm-management.md#registry-authorization) for more details on how to do that.

Fedor Korotkov	5c7743b7cd	Show both size and actual size of files (#742 ) Right now we show only actual size of files on disk which excludes empty blocks of the recently introduced sparced format in #671. This makes impossible to get info about disk size that we just set via `tart set`. Here is an example of `tart list` output before the change: ``` Source Name Size State local sonoma-base 22 stopped local sonoma-vanilla 18 stopped local sonoma-xcode 67 stopped local ubuntu 1 stopped oci ghcr.io/cirruslabs/macos-sonoma-base:latest 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-base@sha256:16c1593bbaf787b20b3c0bc094c5b6baf71c937d22c2e4596da85ac55c92e6cc 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla:14.3 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla@sha256:23c4e853d48d00a4333346d66a32b2b5aad900cc0dc10e7ecb9dbe67b6f587f4 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode:latest 67 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode@sha256:d0cb8d01424a68b89e0f16f5371bf2152b2c115bd886341a6ba8da42121d1f41 67 stopped oci ghcr.io/cirruslabs/ubuntu:22.04 1 stopped oci ghcr.io/cirruslabs/ubuntu@sha256:037763feb7a15d6077edeb7a097738c34313637d16036764b4c196d28d8b429c 1 stopped ``` And here is the output after the change: ``` Source Name Disk Size State local sonoma-base 50 22 stopped local sonoma-vanilla 50 18 stopped local sonoma-xcode 90 67 stopped local ubuntu 20 1 stopped oci ghcr.io/cirruslabs/macos-sonoma-base:latest 50 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-base@sha256:16c1593bbaf787b20b3c0bc094c5b6baf71c937d22c2e4596da85ac55c92e6cc 50 22 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla:14.3 50 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-vanilla@sha256:23c4e853d48d00a4333346d66a32b2b5aad900cc0dc10e7ecb9dbe67b6f587f4 50 17 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode:latest 90 67 stopped oci ghcr.io/cirruslabs/macos-sonoma-xcode@sha256:d0cb8d01424a68b89e0f16f5371bf2152b2c115bd886341a6ba8da42121d1f41 90 67 stopped oci ghcr.io/cirruslabs/ubuntu:22.04 20 1 stopped oci ghcr.io/cirruslabs/ubuntu@sha256:037763feb7a15d6077edeb7a097738c34313637d16036764b4c196d28d8b429c 20 1 stopped ``` Additionally, `tart get` will print actual size with a 3 decimal point precision which will help to track growth in disk images for our templates. `tart get` before: ``` CPU Memory Disk Display State 4 8192 67 1024x768 stopped ``` `tart get` after: ``` CPU Memory Disk Size Display State 4 8192 90 67.333 1024x768 stopped ```	2024-02-27 20:13:38 +04:00

Fedor Korotkov	a48f4d4ec9	Do not magically set `--no-graphics` when `--vnc` is passed (#732 ) From a discussion in #728 it appeared that having both `--graphics` and `--no-graphics` is a bit confusing. `--graphics` was introduced in #248 to support having both VNC and UI for debugging Packer plugin in cirruslabs/packer-plugin-tart#21. This is because `--vnc` flag has a side effect of hiding UI which I think was wrong in retrospective. One can run `tart run --vnc --no-graphics`. In most of the cases this is automated via Alfred or something like that. Now we have so many arguments that IMO it's worth to remove `--graphics` for overall consistency in arguments: everything is enabled by default and can be disabled via `--no-*` flags.	2024-02-19 08:47:27 -05:00
