[gocanto]

Walkthrough

The Dockerfile for the API container was updated to refine user creation, set the working directory to the application user's home, and improve file ownership management by using the --chown flag during file copy operations. A build argument for the application host port was added, and the .env file copy step was removed.

Changes

File(s)	Change Summary
docker/dockerfile-api	Refined user creation, set working directory, improved file ownership with --chown, added APP_HOST_PORT build arg, removed .env copy step.

Poem

In Docker’s warren, changes hop along,
Ownership set right where files belong.
A home for the user, a port in the sun,
The .env file’s journey is finally done.
With chown in the copy, the build hops anew—
A container’s fresh burrow, neat and true!

🔇 Additional comments (6)

docker/dockerfile-api (6)

82-82: Good addition for configurability.

Adding the APP_HOST_PORT build argument makes the Dockerfile more flexible by allowing the exposed port to be configured at build time.

---

86-87: Improved user creation with explicit home directory.

Explicitly setting the home directory with -h ${APP_HOME} ensures the user has the correct home path, which aligns well with the subsequent WORKDIR command.

---

89-90: Good working directory setup.

Setting the working directory to the user's home directory ensures subsequent commands run in the correct context, and the comment clearly explains the intent.

---

96-98: Efficient ownership management with --chown flag.

Using --chown during the COPY operation is more efficient than copying files and then changing ownership afterward, as it reduces the number of layers and operations.

---

103-106: Consistent ownership management for binary.

Applying the same --chown optimization to the binary copy ensures consistent ownership management throughout the Dockerfile.

---

117-118: Proper security practice with user switching.

Switching to the non-root user before EXPOSE and CMD follows Docker security best practices. The recursive chown command on line 115 is still needed for directories created by mkdir, so the combination of --chown flags and the recursive chown provides comprehensive ownership management.

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
