Detailed Guide

While Microsoft provides articles on both scenarios, the Docker setup wasn’t straightforward for me. So, I’ve documented the steps I took to get it running in my environment.

Following the steps in the Docker support article worked, but I faced some timeouts in my setup and had to make additional changes.

Steps to integrate

Step 1 – Clone the Repository : Clone the Synapse VS Code Dev Container sample.

Step 1.5 –  Modify the DockerFile : Open the samples/.devcontainer/mariner folder and update the following section:

# Install PySpark in the base Conda environment
ENV SPARK_VERSION=3.4.1
RUN conda install -c conda-forge pyspark==${SPARK_VERSION}

to

# Install PySpark in the base Conda environment
RUN conda install -c conda-forge mamba # Install Mamba
ENV SPARK_VERSION=3.4.1
RUN mamba install -c conda-forge pyspark==${SPARK_VERSION} # Use Mamba

Step 2 – Open the samples subfolder : From the repository root, open the samples subfolder. Ignore the repo discovery warning in VS Code.

Step 2.5 – Reopen in container : In VS Code, press CTRL + Shift + P to open the command palette manually and select ‘Reopen in Container’.
