Dockerfile how to stop aborting sudo prompt and install apps from bash script

Question

I have a Dockerfile that runs a bash script:

RUN curl -fsSL URL/remote-setup.sh | bash

$URL/remote-setup.sh snippet

curl -L $URL/tarball/master | tar -xzv -C $HOME/output_dir --strip-components=1
. "$HOME/output_dir/setup.sh"

$HOME/output_dir/setup.sh snippet

echo "Make sure we’re using the latest repositories"
    apt update

    echo " Upgrade any already-installed packages"
    apt upgrade

    apps=(
        awscli
        git
        golang-go
        mysql-server
        postgresql postgresql-contrib
        screenfetch
        tig
        tree
        zip
        zsh
    )
    echo "Installing..."
    apt install "${apps[@]}"
    unzip aws-sam-cli-linux-x86_64.zip -d sam-installation

OUTPUT has error

The unzip command & other commands were not found because the list of apps were not installed. It needs to continue with Y rather than abort

Tried adding ENV DEBIAN_FRONTEND noninteractive but doesnt work how do I fix it? thanks

Answer 1

You need to add -y at the end of your installation command... so that, apt continues installation without prompt... So, your final script should be something like below

echo "Make sure we’re using the latest repositories"
    apt update -y

    echo " Upgrade any already-installed packages"
    apt upgrade -y

    apps=(
        awscli
        git
        golang-go
        mysql-server
        postgresql postgresql-contrib
        screenfetch
        tig
        tree
        zip
        zsh
    )
    echo "Installing..."
    apt install "${apps[@]}" -y
    unzip aws-sam-cli-linux-x86_64.zip -d sam-installation

Hope this helps...
