These containers provide pre-configured, isolated environments tailored for development in specific programming languages. For information about cloud and DevOps specific containers, see Cloud and DevOps Containers. Language-specific containers form a core part of the VS Code Dev Containers system, offering ready-to-use development environments with appropriate language runtimes, tools, and best-practice configurations. These containers help developers quickly set up consistent environments without manually installing and configuring development tools.

Sources: - containers/python-3/.devcontainer/Dockerfile - containers/go/.devcontainer/Dockerfile - containers/cpp/.devcontainer/Dockerfile The following language-specific containers are available in the repository: Sources: - containers/python-3/history/dev.md - containers/java/history/dev.md - containers/java-8/history/dev.md - containers/go/history/dev.md - containers/cpp/history/dev.md - containers/dotnet/history/dev.md - containers/php/history/dev.md - containers/alpine/history/dev.md Python containers are among the most extensively developed in the repository, with multiple variants to support different Python versions and specialized environments.

Standard Python containers include Python runtime with common development tools: - Python versions: 3.6, 3.7, 3.8, 3.9, 3.10 - OS bases: Debian Bullseye, Debian Buster - Common Python tools installed with pipx: - pylint, flake8, autopep8, black, yapf, mypy, pydocstyle, pycodestyle, bandit - Optional Node.js installation via nvm Example configuration in devcontainer.json: Special Python variants for data science work: - Python with Miniconda: - Based on Miniconda for lighter weight - Includes Python 3.9 - Supports custom conda environments - Python with Anaconda: - Full Anaconda distribution (2022.05) - Includes Python 3.9 - Pre-installed Jupyter Notebooks and Jupyter Lab - Data science libraries (numpy, pandas, etc.) - Python with PostgreSQL: - Combines Python with PostgreSQL database - Uses Docker Compose to run separate containers - Includes database connection libraries Sources: - containers/python-3/history/dev.md - containers/python-3/.devcontainer/Dockerfile - containers/python-3/.devcontainer/base.Dockerfile - containers/python-3/.devcontainer/devcontainer.json - containers/python-3-anaconda/history/dev.md - containers/python-3-miniconda/history/dev.md - containers/python-3-postgres/.devcontainer/Dockerfile - containers/python-3/README.md Java containers provide pre-configured environments for Java development: - JDK versions: 8, 11, 17 - OS bases: Debian Bullseye, Debian Buster - Tools included: - SDKMAN!

for Java version management - Build tools (available through SDKMAN!) - Common development utilities Java containers have a consistent structure with the specified Java version installed via SDKMAN!, providing flexibility for Java version management. Example configuration in devcontainer.json: Sources: Go containers provide environments specifically tuned for Go development: - Go versions: 1.18, 1.19 - OS bases: Debian Bullseye, Debian Buster - Pre-installed Go tools: - gopls (Go language server) - golangci-lint (linter) - delve (debugger) - And other common Go tools: golang.org/x/tools, golang.org/x/lint, etc.

Example configuration in devcontainer.json: Sources: - containers/go/history/dev.md - containers/go/.devcontainer/Dockerfile - containers/go/.devcontainer/devcontainer.json - containers/go/README.md C++ containers provide environments for C++ development with multiple compiler options: - OS variants: Debian 11, Debian 10, Ubuntu 22.04, Ubuntu 20.04, Ubuntu 18.04 - Compilers: - GCC (version varies by OS: 10.2.1 for Debian 11, 8.3.0 for Debian 10, etc.) - Clang (version varies by OS) - Build tools: CMake, Ninja - Debuggers: GDB, LLDB - Package management: vcpkg The C++ containers include special configurations for debugging, such as additional Docker capabilities for debug tools.

For example, the Python container is now being published from devcontainers/images/src/python Sources: Refresh this wiki - Language-Specific Containers - Overview - Container Structure and Architecture - Available Language Containers - Python Containers - Standard Python Containers - Python Data Science Variants - Java Containers - Go Containers - C++ Containers - Other Language Containers - .NET Containers - PHP Containers - Rust Containers - Alpine Containers - Community-Maintained Containers - Common Components Across Language Containers - Using Language-Specific Containers - Version Selection - Node.js Integration - Customizing Language Containers - Installing Additional Packages - Installing Language-Specific Packages - Using Post-Create Commands - Migration Notice
