I am following a tutorial that can be found here to set up a headless selenium scraper on an ec2 instance:

https://krbnite.github.io/Driving-Headless-Chrome-with-Selenium-on-AWS-EC2/

The tutorial I am using seems to assume an ubuntu distro whereas the ec2 instance I am using is an AWS AMI. As such apt-get is not available to me and instead I use yum to install things.

The first step of the installation process is the following:

wget -q -O - "https://dl-ssl.google.com/linux/linux_signing_key.pub" | sudo apt-key add -

When I do this I get the following, to be expected error on my AWS AMI instance:

sudo: apt-key: command not found

I was wondering what the equivalent command would be without using apt, apt-get, or apt-key but instead using yum. I have blindly tried the following but they did not work:

wget -q -O - "https://dl-ssl.google.com/linux/linux_signing_key.pub" | sudo yum add -

wget -q -O - "https://dl-ssl.google.com/linux/linux_signing_key.pub" | sudo yum-key add -

Thanks

    `wget -q -O /path/to/key "https://dl-ssl.google.com/linux/linux_signing_key.pub"; rpm --import /path/to/key`. – alvits May 03 '18 at 01:47

Below is from an article on Baeldung which I think answers this questions properly:

Adding a repository in YUM is a manual operation, which consists in creating a file with the .repo extension under the folder /etc/yum.repos.d.

The file must contain all the information about the custom repository that we are connecting to.

Let’s try adding the AdoptOpenJDK repository:

# /etc/yum.repos.d/adoptopenjdk.repo
[AdoptOpenJDK]
name=AdoptOpenJDK
baseurl=http://adoptopenjdk.jfrog.io/adoptopenjdk/rpm/centos/7/$(uname -m)
enabled=1
gpgcheck=1
gpgkey=https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public

In APT, though, things are quite different. The GPG key of the repository must be downloaded and added to the APT keyring with apt-key add:

wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -

Then, at this point, the repository can be added through add-apt-repository –yes followed by the URL:

add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/

Contrary to YUM, all the repositories are saved in a single file, /etc/apt/sources.list.

Add the repo and then import the repo GPG key

sudo wget -o /etc/yum.repos.d/reponame.repo <repo url>
sudo rpm --import <key url>

Confirm

yum repolist
