Sentry is a crash reporting platform that provides you with "real-time insight into production deployments with info to reproduce and fix crashes". It notifies you of exceptions or errors that your users run into while using your app and organizes them for you on a web dashboard.

Let's install & Setup Sentry on Docker Container using the CentOS platform, but you can use any other platform as well.

In our script, we will install the below containers.

Before we start with Sentry installation, please make sure your base operating system is ready with CentOS or Ubuntu and also install Docker on top of it. 

To install Docker please follow the below official docker documentation: 

Also, you can download all below files from the below github link:

Create .envpostgres under env directory and add below lines.

Create .envsentry file under env directory add below lines

SENTRY_SECRET_KEY=Hhdjabcjajaajhjaa12121jk

SENTRY_URL_PREFIX=https://sentry.domain.com

SECURE_PROXY_SSL_HEADER=('HTTP_X_FORWARDED_PROTO', 'https')

To Deploy all required containers DB for Sentry:

docker run -d --name sentry-postgres --env-file env/.envpostgres -v /root/container-backup/sentry/postgress:/var/lib/postgresql/data postgres && \
secret_key=$(docker run --rm sentry config generate-secret-key) && \
docker volume create --driver local --opt type=none --opt device=/root/container-backup/sentry/config --opt o=bind sentry-config
docker run -it --rm -e SENTRY_SECRET_KEY=${secret_key} -p 9000:9000 --link sentry-postgres:postgres --link sentry-redis:redis sentry upgrade && \
docker run -d --name sentry -e SENTRY_SECRET_KEY=${secret_key} --env-file env/.envsentry -p 9000:9000 -v sentry-config:/etc/sentry -v /root/container-backup/sentry/files:/var/lib/sentry --link sentry-redis:redis --link sentry-postgres:postgres sentry && \
docker run -d --name sentry-cron -e SENTRY_SECRET_KEY=$secret_key --env-file env/.envsentry -v sentry-config:/etc/sentry -v /root/container-backup/sentry/files:/var/lib/sentry --link sentry-postgres:postgres --link sentry-redis:redis sentry run cron && \
docker run -d --name sentry-worker-1 -e SENTRY_SECRET_KEY=${secret_key} --env-file env/.envsentry -v sentry-config:/etc/sentry -v /root/container-backup/sentry/files:/var/lib/sentry --link sentry-postgres:postgres --link sentry-redis:redis sentry run worker

To enable NGINX proxy please use below method. (optional)

Create nginx.conf file under nginx directory and add below lines:

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

events {
    worker_connections 1024;
}

http {
    log_format main
 '$remote_addr - $remote_user [$time_local] "$request" '
 '$status $body_bytes_sent "$http_referer" '
 '"$http_user_agent" "$http_x_forwarded_for"';

    access_log /var/log/nginx/access.log main;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    include /etc/nginx/conf.d/*.conf;

       listen         80;
       server_name    sentry.domain.com;
       return         301 https://$server_name$request_uri;

   server {

            proxy_set_header    Host $host;
            proxy_set_header    X-Real-IP $remote_addr;
            proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header    X-Forwarded-Host $server_name;

            proxy_pass http://localhost:9000;
     }

        }
  } ##End of main HTTP

Generate & Add your own SSL certificate and SSL key under SSL directory. Refer:  

Now deploy NGINX docker container using below commands:

docker run -p 443:443 --name nginx -v $(pwd)/nginx/nginx.conf:/etc/nginx/nginx.conf -v $(pwd)/ssl:/etc/nginx/ssl -d nginx

To verify, if the docker containers are running or not

Once everything is up and working, please use your defined URL in any of your favorite browser https://sentry.domain.com
