Some files - those maintained by external organizations - have a very light treatment and solely point to the upstream documentation to reduce any issues creating examples/documentation for them that may differ in the future.
Closes#7315
The ingress-nginx ingress implementation is the standard ingress in the Kubernetes community, and it doesn't make sense for us to stray from that just to utilize the k3s default.
In the future, we might drop k3s, but this works well for now.
Rather than require a heavy chown operation across various paths, just chown the files already in the built image during the release process. This ensures we can skip not-only the chown process during the container start that herokuish injects, but also the one that Dokku runs which modifies mounted container paths as well during the pre-deploy.
Note that users will need to ensure any mounted volumes don't have permissions reset by other processes or containers won't be able to access them.
Building/testing for ARM does not happen often - the only runtime environment is Raspberry PI, which supports ARM64 - and complicates support for a ton of features. Aside from that, CI runs are much longer for ARM Dokku images, often reaching 15-20 minutes or just timing out completely.
Rather than support an architecture that doesn't have much usage by maintainers and has a lot of maintenance burden, we're removing the platform.
AMD64 and ARM64 continue to be supported, but ARM in CI is not currently supported and doesn't get local testing either, so deprecating it now and removing it in the future makes most sense for the project.
This change converts existing CHECKS files into a healthchecks key that is understood by 'docker-container-healthchecker'. This tool supports a number of different types of container healthchecks - command, http, uptime - and can perform healthchecks against non-web processes.
The use of the old CHECKS file is now deprecated, and will be removed in the next minor version. Users can use the 'docker-container-healthchecker' to convert existing CHECKS files to the new format automatically.
Closes#2760
Previously, we would always set the port mapping during a dockerfile build, making it difficult for users to override mappings. We also only _sometimes_ updated the detected port mapping, further confusing issues when users were migrating from Dockerfile to Buildpacks for builds.
Now, we always detect the port mapping during the build process, and only use that detected port mapping if an override is not specified. This greatly simplifies the experience around port mapping, as now a user can create an app, set a port mapping, and that first deploy will respect the port mapping without an additional deploy.
The builder always has the best context for what the app should be listening on, and thus we can always specify a "default" port mapping at this stage. Users can override this map as desired later.
This change also results in the removal of a ton of internal code that is now centralized in the ports plugin.
Closes#4067
This makes deploys faster for any that are built from source as the image artifact isn't involved in those cases while also unifying how the file is handled.
Refs #2760
This ensures users don't have issues with cached state in regards to files pulled from the repo/image.
Also add missing docs for deploy-source-set trigger.
Closes#5963
