PR Review 🔍

⏱️ Estimated effort to review [1-5]	3, because the PR involves changes across multiple Dockerfiles and a Rust source file, which requires understanding of both Rust and Docker configurations. The logic for toggling JSON logs based on an environment variable also needs careful review to ensure it functions as intended.
🧪 Relevant tests	No
⚡ Possible issues	Possible Bug: The use of env::var_os("JSON_LOGS").is_some() for toggling JSON logs might not be robust enough. It will be true for any non-empty value, which could lead to unintended behaviors if the environment variable is set incorrectly.
🔒 Security concerns	No

Code feedback:

---

relevant file	src/infra/tracing.rs
suggestion	Consider using a more explicit check for enabling JSON logs. For example, check for a specific value like "true" to avoid confusion and potential errors if the environment variable is set to an unintended value. [important]
relevant line	let json_logs = env::var_os("JSON_LOGS").is_some();

PR Code Suggestions ✨

Category	Suggestions
Best practice	Improve error handling during logging subscriber initialization. Consider using tracing_subscriber::fmt().try_init() instead of subscriber.init() to handle potential errors during the initialization of the subscriber. src/infra/tracing.rs [42-44] -subscriber.json().init(); -subscriber.compact().init(); +subscriber.json().try_init().expect("Failed to initialize JSON logging"); +subscriber.compact().try_init().expect("Failed to initialize compact logging");
	Explicitly define the environment filter for the tracing subscriber for better control. Use tracing_subscriber::EnvFilter directly instead of EnvFilter::from_default_env() to explicitly define the environment filter for better clarity and control. src/infra/tracing.rs [38] -.with_env_filter(EnvFilter::from_default_env()); +.with_env_filter("info,my_crate=debug");
	Use consistent method for environment variable checks. Instead of using env::var_os("JSON_LOGS").is_some(), use env::var("JSON_LOGS").is_ok() for consistency with other environment variable checks in the code. src/infra/tracing.rs [40] -let json_logs = env::var_os("JSON_LOGS").is_some(); +let json_logs = env::var("JSON_LOGS").is_ok();
Maintainability	Refactor subscriber initialization into a separate function for better maintainability. Refactor the conditional logic for initializing the subscriber into a separate function to improve code readability and maintainability. src/infra/tracing.rs [41-44] -if json_logs { - subscriber.json().init(); -} else { - subscriber.compact().init(); +init_subscriber(subscriber, json_logs); + +fn init_subscriber(subscriber: Subscriber, json_logs: bool) { + if json_logs { + subscriber.json().init(); + } else { + subscriber.compact().init(); + } }
