Alpine Linux Agent Installation

IMPORTANT: Beginning January 31, 2023, the agent end-of-support policy will take effect. Per this policy, we will support agent versions that are under two years old. On a quarterly cadence, we will deprecate and no longer support agent versions that are older than two years. At the end of January, we will support Agent v4.16.0 and above. If you need help upgrading your agent to a supported version, contact securitysupport@fastly.com.

Run the Alpine Docker container

If Alpine is being run in a Docker container, start the container. For example:

docker run -it -p 80:80 alpine:3.11 /bin/sh

Add the package repository

Alpine in Container

On the running Alpine container, run the following script:

apk update
apk add wget
wget -q https://apk.signalsciences.net/sigsci_apk.pub ; mv sigsci_apk.pub /etc/apk/keys/
echo https://apk.signalsciences.net/3.11/main | tee -a /etc/apk/repositories && apk update

Alpine in VM or bare-metal

If running Alpine on a VM or bare-metal, run the following script:

sudo apk update
sudo apk add wget
sudo wget -q https://apk.signalsciences.net/sigsci_apk.pub ; sudo mv sigsci_apk.pub /etc/apk/keys/
sudo echo https://apk.signalsciences.net/3.11/main | sudo tee -a /etc/apk/repositories && sudo apk update

Verify the downloaded key

Verify the downloaded key contains the proper key by running the following command:

openssl rsa -pubin -in /etc/apk/keys/sigsci_apk.pub -text -noout

If the downloaded key contains the proper key, the expected output will be:

Public-Key: (2048 bit)
