- [PR-151](https://github.com/itk-dev/devops_itkdev-docker/pull/151) - 2026-09-14 -
Fixed the SSL section of the README: the certificate path read `treafik`,
and the `openssl` config path was the Intel Homebrew prefix, so the
documented command failed on Apple Silicon
- [PR-145](https://github.com/itk-dev/devops_itkdev-docker/pull/145) - 2026-07-08 -
Updated GitHub Actions to latest versions (`actions/checkout` to `v7`,
`go-task/setup-task` to `v2`) in workflow templates and repository CI

by using this openssl command on Mac, just change the two places where the domain is written.

```sh
openssl req -x509 -sha256 -nodes -days 3650 -newkey rsa:2048 -keyout docker.key -out docker.crt -subj "/CN=*.local.itkdev.dk" -reqexts SAN -extensions SAN -config <(cat /usr/local/etc/openssl/openssl.cnf <(printf '[SAN]\nsubjectAltName=DNS:*.local.itkdev.dk'))
openssl req -x509 -sha256 -nodes -days 3650 -newkey rsa:2048 -keyout docker.key -out docker.crt -subj "/CN=*.local.itkdev.dk" -reqexts SAN -extensions SAN -config <(cat "$(openssl version -d | cut -d'"' -f2)/openssl.cnf" <(printf '[SAN]\nsubjectAltName=DNS:*.local.itkdev.dk'))
```

`openssl version -d` finds the config wherever Homebrew put it, on Intel (`/usr/local`) as well as Apple Silicon
(`/opt/homebrew`).

The wildcard covers one level only, so `foo.local.itkdev.dk` matches but `foo.bar.local.itkdev.dk` does not. Add a
`DNS:` entry per level you need; a double wildcard, `*.*.local.itkdev.dk`, matches nothing at all.

To mac browser trust this certificate you need to open it with key-chain right click and select "Get info" and then open
the "Trust" tab and select "Always trust".

The certificate is located in `./treafik/ssl/docker.crt` in this repository.
