Container App wont run but docker run works fine

Question

I am confused and couldn't find much info on this issue. I have a docker image based on ubuntu 20.4 image and runs a bunch of scripts. Using docker run locally works and the container function as it should, but Once I deploy the image to container app, I cannot see the log stream or access the console and no error. It stuck in processing state.

My docker image has CMD and ENTRYPOINT setup like this:

ENTRYPOINT ["./start_script.sh"]
CMD [ "sleep", "infinity" ]

I have included the container app command like

command = ["/bin/bash","-c","./start_script.sh"]

Any idea what I am missing ? I will appreciate.

Below is the docker file

# Use Ubuntu 20.04 LTS as the base image
FROM ubuntu:20.04

# Avoid prompts from apt
ENV DEBIAN_FRONTEND=noninteractive

# Update apt repositories and install necessary packages
RUN apt-get update && apt-get install -y \
    software-properties-common \
    curl \
    lsb-release \
    gnupg \
    python3-pip

RUN python3 -m pip install pip --upgrade \
    && pip install pyopenssl --upgrade

# Install Certbot
RUN apt-get install -y certbot

# Install certbot-dns-azure plugin via pip
RUN pip3 install certbot-dns-azure

# Install cron
RUN apt-get install -y cron

# Install Azure CLI
RUN curl -sL https://aka.ms/InstallAzureCLIDeb | bash

# Clean up
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

# Create a directory for scripts and the credentials file
WORKDIR /app

# Copy your scripts and credentials file into the image
COPY start_script.sh combine_and_upload.sh renew_script.sh azure_credentials.ini ./

# Set the appropriate permissions for the credentials file and make scripts executable
RUN chmod 600 azure_credentials.ini \
    && chmod +x start_script.sh combine_and_upload.sh renew_script.sh

# Set the entry point to your start script
ENTRYPOINT ["./start_script.sh"]
CMD [ "sleep", "infinity" ]

I run it locally as like:

run -d --name certbot-container -e KEYVAULT_NAME=xxx -e CERT_KEY_NAME=xxx -e DEVOPS_EMAIL=xxx -e DOMAIN=xxx -e AZURE_TENANT_DOMAIN=xxx -e CERT_NAME=xxxx registry.xxx/xxx/xx/services/certbot:v1

Answer 1

I guess as your docker run command to execute isn't taking any additional arguments(nothing after image name)

So you should just remove this part from your Tarraform file

            command = [
              "/bin/bash",
              "-c",
              "./start_script.sh"
            ]

And everything should work
