Sentry self-hosted (getsentry/self-hosted 26.8.0) could not be deployed
as a Docker Compose application. Three separate problems blocked it:
- YAML collection aliases: the first fix raised the limit to 256 only in
Application::oldRawParser(). The safety check added in v4.4.0
(validateDockerComposeForInjection) and all other Compose parse calls
still used the Symfony default of 128, so the Sentry file (133 aliases)
failed with "Maximum number of collection aliases (128) exceeded".
Add parseDockerComposeYaml() and use it for every Compose parse.
- Argument list too long: the deployment job sent the generated Compose
file as base64 inside the SSH command. Linux limits one argument to
128 KiB, and the Sentry file is about 370 KB. execute_remote_command()
now accepts an 'input' key that streams content over SSH stdin, and
the job writes the Compose file with it.
- A list-style build arg without a value (build.args: [SENTRY_IMAGE])
merged into a map environment kept its numeric key, so Docker Compose
rejected the file with "non-string key in ...environment: 0". It now
becomes NAME with no value, as in Compose.
Closes#11725
