Experiencing a smart compile problem with Zimbra 10.1.10.p2? You're not alone! This article dives deep into a specific issue encountered while building Zimbra 10.1.10.p2 using the smart image, provides a detailed breakdown of the problem, and explores potential solutions and workarounds. Whether you're a seasoned Zimbra administrator or just getting started, this guide will help you navigate this tricky situation and get your build process back on track.

Understanding the Smart Compile Issue

The Initial Problem

A user recently reported a problem when trying to compile the build 10.1.10.p2 with the smart image, a process that had worked seamlessly before. The user followed a standard procedure, utilizing Docker to build the image. Let's break down the commands they used:

First, the Docker image was built using the following command:

docker build \
  --build-arg ZIMBRA_BUILDER_UID=$(id -u) \
  --build-arg ZIMBRA_BUILDER_GID=$(id -g) \
  --tag zimbra-smart-ubuntu-22.04-builder . \
  -f Dockerfile-smart-ubuntu-22.04

This command uses the docker build command to create a new Docker image. Let's dissect the options:

  • --build-arg ZIMBRA_BUILDER_UID=$(id -u): This sets the build argument ZIMBRA_BUILDER_UID to the user ID of the current user. This is important for permissions within the container.
  • --build-arg ZIMBRA_BUILDER_GID=$(id -g): Similarly, this sets the ZIMBRA_BUILDER_GID build argument to the group ID of the current user.
  • --tag zimbra-smart-ubuntu-22.04-builder: This tags the resulting image with the name zimbra-smart-ubuntu-22.04-builder, making it easier to reference later.
  • .: This specifies the build context as the current directory.
  • -f Dockerfile-smart-ubuntu-22.04: This specifies the Dockerfile to use, in this case, Dockerfile-smart-ubuntu-22.04.

Next, the Docker image was run with this command:

docker run \
  -it \
  --env ZIMBRA_BUILDER_UID=$(id -u) \
  --env ZIMBRA_BUILDER_GID=$(id -g) \
  --env ZM_BUILD_RELEASE_NO='10.1.10p2' \
  --env PIMBRA_ENABLED='pimbra-disabled' \
  --env ZM_BUILDER_ID='431' \
  -v ~/.ssh:/home/build/.ssh:ro \
  -v $(pwd):/usr/local/zimbra-foss-builder:ro \
  -v $(pwd)/BUILDS:/home/build/installer-build/BUILDS:rw \
  zimbra-smart-ubuntu-22.04-builder:latest

This command uses docker run to start a container from the previously built image. Let's break down these options as well:

  • -it: This runs the container in interactive mode, allowing you to interact with it via the terminal.
  • --env ZIMBRA_BUILDER_UID=$(id -u): Sets the ZIMBRA_BUILDER_UID environment variable within the container, mirroring the build argument.
  • --env ZIMBRA_BUILDER_GID=$(id -g): Sets the ZIMBRA_BUILDER_GID environment variable, again mirroring the build argument.
  • --env ZM_BUILD_RELEASE_NO='10.1.10p2': Sets the ZM_BUILD_RELEASE_NO environment variable to 10.1.10p2, specifying the Zimbra release number.
  • --env PIMBRA_ENABLED='pimbra-disabled': Disables the PIMBRA feature by setting the PIMBRA_ENABLED environment variable.
  • --env ZM_BUILDER_ID='431': Sets the ZM_BUILDER_ID environment variable to 431.
  • -v ~/.ssh:/home/build/.ssh:ro: Mounts the user's SSH directory into the container in read-only mode. This allows the build process to access SSH keys for authentication.
  • -v $(pwd):/usr/local/zimbra-foss-builder:ro: Mounts the current directory (where the zimbra-foss-builder repository is likely located) into the container in read-only mode.
  • -v $(pwd)/BUILDS:/home/build/installer-build/BUILDS:rw: Mounts the BUILDS directory in the current directory into the container in read-write mode. This is where the build output will be stored.
  • zimbra-smart-ubuntu-22.04-builder:latest: Specifies the image to run, using the tag we assigned earlier.

The Error Encountered

While this process worked flawlessly until version 10.1.10.GA.4310000.UBUNTU22.64, the user encountered a perplexing error when running the second command (the docker run command). The build process exited with the following error message:

[...] 
Resolving deltas: 100% (85364/85364), done. 
/usr/local/zimbra-foss-builder/zm-build-tag-helper.sh: line 20: ../: Is a directory 
cat: zm-build-branch.txt: No such file or directory 
ZM_BUILD_BRANCH is not defined.

This error message indicates a problem with the zm-build-tag-helper.sh script, specifically on line 20. The script seems to be having trouble determining the build branch, as evidenced by the missing zm-build-branch.txt file and the undefined ZM_BUILD_BRANCH variable.

Breaking Down the Error Message

Let's analyze the error message in detail:

  • Resolving deltas: 100% (85364/85364), done.: This part of the output is related to Git and indicates that the process of resolving differences between versions in the repository has completed successfully. This suggests that the initial Git operations were successful.
  • /usr/local/zimbra-foss-builder/zm-build-tag-helper.sh: line 20: ../: Is a directory: This is the first error message and suggests that the script is trying to treat a directory as a file. The ../ likely refers to navigating one level up in the directory structure, and the script is failing when it encounters a directory instead of a file.
  • cat: zm-build-branch.txt: No such file or directory: This error indicates that the script is trying to read a file named zm-build-branch.txt, but the file does not exist in the expected location. This is a critical clue for troubleshooting.
  • ZM_BUILD_BRANCH is not defined.: This error message confirms that the ZM_BUILD_BRANCH environment variable is not being set or cannot be determined by the script. This variable is crucial for identifying the branch being built.

Potential Causes and Troubleshooting Steps

Now that we have a clear understanding of the error, let's explore potential causes and troubleshooting steps.

1. Missing zm-build-branch.txt File

The most obvious issue is the missing zm-build-branch.txt file. This file is likely supposed to contain the name of the Git branch being built. Here's how we can investigate this:

  • Check the Repository: Verify that the zm-build-branch.txt file exists in the zimbra-foss-builder repository on the branch you are trying to build. You can do this by navigating to the repository in your file system or using Git commands.
  • Git Status: Run git status within the zimbra-foss-builder directory to check for any uncommitted changes or files that might be causing issues. Ensure that the repository is in a clean state.
  • Git Branch: Run git branch to confirm that you are on the correct branch. Sometimes, being on the wrong branch can lead to missing files.

2. Script Error in zm-build-tag-helper.sh

The error message ../: Is a directory suggests a potential issue within the zm-build-tag-helper.sh script itself. Let's examine this script:

  • Inspect the Script: Open the zm-build-tag-helper.sh script and examine line 20. The error message indicates that the script is trying to perform an operation on a directory as if it were a file. Identify the command on line 20 and analyze why it might be encountering a directory instead of a file.
  • Check File Paths: Ensure that all file paths used in the script are correct and that the files they are pointing to actually exist. Incorrect file paths can lead to the script trying to access a directory instead of a file.
  • Debugging: Add debugging statements to the script (e.g., using echo to print variable values) to trace the execution flow and identify where the error occurs. This can help pinpoint the exact cause of the issue.

3. Environment Variable Issues

The error ZM_BUILD_BRANCH is not defined indicates that the ZM_BUILD_BRANCH environment variable is not being set correctly. This variable is likely crucial for the build process.

  • Dockerfile Inspection: Examine the Dockerfile-smart-ubuntu-22.04 file to see how the ZM_BUILD_BRANCH environment variable is supposed to be set. Look for any ENV instructions related to this variable.
  • Docker Run Command: Review the docker run command to ensure that the ZM_BUILD_BRANCH environment variable is being passed correctly. It's possible that the variable is not being set in the command or that there's a typo in the variable name.
  • Script Logic: Check the zm-build-tag-helper.sh script to see how it uses the ZM_BUILD_BRANCH variable. Ensure that the script is correctly accessing and using the variable.

4. Docker Volume Mount Issues

Incorrectly mounted volumes can also lead to file access issues within the container.

  • Volume Paths: Double-check the volume mount paths in the docker run command. Ensure that the paths are correct and that the host directories exist.
  • Permissions: Verify that the user within the container has the necessary permissions to access the mounted volumes. Permission issues can prevent the script from reading or writing files.

5. Git Repository State

A corrupted or inconsistent Git repository state can sometimes cause build issues.

  • Clone Again: Try cloning the zimbra-foss-builder repository again into a new directory. This will ensure that you have a clean copy of the repository.
  • Git Reset: If you suspect local changes might be causing issues, try running git reset --hard HEAD to discard any uncommitted changes and reset the repository to the latest commit.

Potential Solutions and Workarounds

Based on the troubleshooting steps, here are some potential solutions and workarounds:

  • Ensure zm-build-branch.txt Exists: If the zm-build-branch.txt file is missing, try creating it manually with the correct branch name. This might be a temporary workaround, but it can help you proceed with the build.

  • Fix Script Error: If you identify an error in the zm-build-tag-helper.sh script, correct the script and try the build again. This is the most sustainable solution.

  • Set ZM_BUILD_BRANCH Manually: If the ZM_BUILD_BRANCH environment variable is not being set, try setting it manually in the docker run command. For example:

    docker run ... --env ZM_BUILD_BRANCH=<your_branch_name> ...

  • Verify Volume Mounts: Double-check the volume mount paths and permissions to ensure they are correct.

  • Clean Git Repository: If you suspect a Git issue, try cloning the repository again or resetting it to a clean state.
