Self-Hosted Deployment of Sentry over AWS

Hello Readers. This will be a blog series on Self-hosted Sentry deployment over AWS. In the 1st blog of this series, I’ll be deploying a self-hosted Sentry server. Before starting up with deployment, let’s first understand what Sentry is and what does it provide.

What is Sentry?

Sentry is a service that helps you monitor and fix crashes in real-time. It helps in tracking errors and also provide with information to reproduce the issue and fix crashes. Apart from this, it also provides insights into production deployments, all that in real-time. Some of its prominent features include

• Consolidates similar error and make their resolution easy
• Huge list of supported platforms.
• Provide Hosted and Self Hosted service
• Multiple integrations available including GitHub and Slack
• Allow Email Notification and many more…

Setting up Self-Hosted Sentry Server

Sentry provides a separate GitHub repository for Self-Hosted Server. To deploy the server, you can run the following steps.

Setup Instance

Launch an instance over AWS. The instance should have at least 4GB RAM and 2 CPU Core for better performance. For AWS, I’ll recommend to go with t2.medium instance.
Configure the instance by installing docker and docker-compose.

Installing docker

## Install Dependencies for docker
sudo apt-get install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

## Install Docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt-get update -y && sudo apt-get install -y docker-ce docker-ce-cli containerd.io

Installing docker-compose

## Installing docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

## Make docker-compose executable
sudo chmod +x /usr/local/bin/docker-compose

Run docker without sudo

sudo groupadd docker
sudo usermod -aG docker $USER
## Reboot the instance

Install sentry

## Clone the sentry repository
git clone https://github.com/getsentry/onpremise.git

After cloning the repository, Install Sentry with default configurations using the following command

## Run installation script
cd onpremise/
./install.sh --no-user-prompt
docker-compose up

Final Note

As specified, the above-mentioned commands will install Sentry with the default configurations and its dashboard will now be accessible on <instance-ip>:9000.
To modify those default configurations, we need to modify onpremise/sentry/config.yml and onpremise/sentry/sentry.conf.py.
Sentry will also generate a log file sentry_install_log-<TIMESTAMP>.txt over the instance with the output logs of Sentry installation script install.sh.
