通过 Docker、bash 将 CDK 部署到 AWS 时：cdk: command not found

Question

Present are two files, Dockerfile.infra and docker-compose-infra.yml . Firstly, docker-compose-infra.yml is built via the following command:

docker-compose --file docker-compose-infra.yml build

This results in no errors and finishes as expected.

The problem arises when trying to deploy this to AWS. The following command:

docker-compose --file docker-compose-infra.yml run cdk

Produces this error:

bash: cdk: command not found

This appears to be triggered when the docker-compose-infra.yml attempts to run the cdk deploy bash command.

The command should run because within the Dockerfile.infra build, cdk is installed via npm install -g aws-cdk-lib .

Dockerfile.infra file:

FROM node:16-slim

ENV DEBIAN_FRONTEND=noninteractive

RUN npm install -g aws-cdk-lib  \
    && apt-get update -y \
    && apt-get upgrade -y \
    && apt-get install -y --no-install-recommends \
    # install Python
    python3-pip \
    # install Poetry via curl
    curl \
    && curl -k https://install.python-poetry.org | python3 - \
    && apt-get remove curl -y \
    && apt-get autoremove -y \
    && rm -rf /var/lib/apt/lists/*

COPY pyproject.toml poetry.lock /
ENV PATH=/root/.local/bin:$PATH
RUN poetry config virtualenvs.create false \
    && poetry install --no-dev

WORKDIR /app/
COPY app.py cdk.json cdk.context.json /app/
COPY stacks/ /app/stacks/

docker-compose-infra.yml:

version: "3"
    services:
      cdk:
        command: bash -c "cdk deploy --require-approval never --all --parameters my-app-${ENVIRONMENT}-service:MyServiceImageTag=${IMAGE_TAG}"
        build:
          context: ./
          dockerfile: Dockerfile.infra
        environment:
          - AWS_PROFILE=${AWS_PROFILE}
          - ENVIRONMENT=${ENVIRONMENT}
          - DEPLOY_ACCOUNT=${DEPLOY_ACCOUNT}
        volumes:
          - ~/.aws/credentials:/root/.aws/credentials

Answer 1

You need to install aws-cdk not aws-cdk-lib

RUN npm install -g aws-cdk \

This might be a bit confusing because aws-cdk-lib is also the name of the required Python dependency when writing Python CDK apps and a valid npm package.
