Anyone else using Bitbucket for CI/CD? https://bitbucket.org/blog/macos-runners-bitbucket

I been using Bitbucket for pipelines for a while now. What about the runners?
We are happy to announce that Bitbucket Pipelines now supports macOS self-hosted runners. We have moved from beta to an official…
They’ve added support for macOS.
I’ve been using Bitbucket pipelines for a while as well. I think they do a great job and stay on par with pipeline offerings from GitHub and GitLab.
I think Bitbucket is one of the best pipelines that people don’t think to consider. When i saw this post about new runners, I was just curious what other folks in this community might be using it as well.

In case people are interested I’ll be raising the following topic tomorrow during office hours. I think it’s an interesting one and looking to get people’s feedback on it:

Hey everyone,
Looking to have a bit of a debate on the topic of monitoring as code and whether or not *it actually matters*. More specifically: whether having monitors, dashboards, service level objects and the like actually need to be backed by IaC and within a GitOps workflow.
Many of us have monitoring products like datadog or cloudwatch in which the vast majority of monitors, dashboards, SLOs and the like have been clickops’d. For example at my current shop there are about 350 dashboards and almost none are in IaC and what’s more we don’t really know which ones are critical and which ones can be deleted. And the same goes for monitors and SLOs.
Now imagine that you used Terraformer (or equivalent, if there even is such a thing for Cloudformation) to get all these things into terraform and into all the appropriate repos. And then you even took that a step further and developed a system to do this continuously and also to clean up your monitoring product in the meanwhile, e.g. delete any dashboard not label critical
or something.
My questions to the community are: • so what? All of those clickops’d dashboards are backed up by the CSP or 3rd party; if they have a catastrophic event they’ll probably be able to get them back to you? • and do we really want to be writing dashboards as code? It gets fairly ridiculous. • and as for labeling them and then automating their cleanup: will it be that much of a feng shui or cost improvement? Curious about people’s thoughts regarding this topic because now that I have everything in IaC and a potential solution for automating parity and cleanup I find myself asking, “Who cares?” And of course if there are other reasons for storing monitors, dashboards, SLOs and the like as code please bring those up as I’m always interested in learning how other people are solving problems!

@Erik Osterman (Cloud Posse) I have a meeting that goes until 12PM PT. I can skip it if I need to because I definitely want to raise the observe-as-code debate, but if you have content until 12PM and I can bring that up after that’d be great. Either way just not sure what you have on the agenda today. Thanks!
Ok, we’ll defer it to 12pm
@Erik Osterman (Cloud Posse) no need, I can miss the other meeting – I’ve thought a lot about this today and yesterday and I want to make sure this gets top treatment so I’ll be there during peak.
Random one: I know the official line is that s3 buckets can’t be moved between accounts, but is that really true even at the “ask AWS support nicely” level? We’ve got a few big enough buckets that, on the face of it, it would cost a few k to copy them from one account to another, which is a blocker for my preferred approach of rebuilding key systems in new accounts to get rid of old cruft. Any stories of non-bank-breaking S3 bucket migrations would be interesting!
@david.gregory_slack I’m not sure if you are aware of the s3p library – but if you do end up copying files I cannot recommend it enough – s3p saved me hours, if not days, on cross-account recursive s3 bucket copying. Pro-tip: spin up a huge ec2 instance or container of some type beforehand, as that will also dramatically help parallelization. Fwiw.
list/copy/sync/compare S3 buckets 5x-50x faster than aws-cli
I should have mentioned: this library is an order of magnitude faster than any other library you will find. At least it was when I used it last year.
heads up, we discussed this today
Thanks, hoped to make it but events. Will catch up.

Does anybody have experience with AWS EKS using AWS EFS?
I need a place to store/read some data (5-10MB file) very fast and have it available consistently on multiple pods.

I know there are a number of ways to initialize your vault cluster but personally I am a fan of being able to do things in terraform: https://registry.terraform.io/providers/rickardgranberg/vaultoperator/0.1.6
^^ Sharing in case you folks haven’t heard of it before.

@Erik Osterman (Cloud Posse) - during some of the office hours calls you point to your internal ?confluence? page where you show how you structure aws accounts in an ldap / ou style
is there any chance that page is publicly accessible?

Q: How are people enforcing MFA in AWS? Not using AWS SSO at the moment, just IAM Users and IAM Groups. Have seen a cloudtrail solution that uses a cloudwatch metric filter and alarm which does the trick, but is probably very expensive as you need to use cloudtrail.
Check out the policy in this AWS Doc: https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_examples_aws_my-sec-creds-self-manage-mfa-only.html
The relevant bit is here:

"iam:ResyncMFADevice",
"sts:GetSessionToken"
],
"Resource": "*",
"Condition": {
"BoolIfExists": {"aws:MultiFactorAuthPresent": "false"}
}
}
Use this IAM policy to allow users to manage their MFA device in the AWS Management Console.

We are using a product called gravitational teleport, where mfa is added to github, people login via their github profile and only a particular team has access to the aws console itself
Interesting, thanks. We have some non technical users so doing things through github isn’t as ideal unfortunately
They have enterprise plans as well with AD integration
We are using the free version

Why Terraform data sources are preferable over remote state, with use-cases using multiple filters based on tags to filter resources dynamically
Using the for expression in Terraform to filter, group, order and mutate information. With this knowledge in hand you will easily be able to construct complex objects based on existing information/configuration or from configuration passed in via input variables or ingested. Easily create multiple instances of resources or data sources using the for_each meta-argument.
