  • manager: Anthony Schaller, +1 510-541-5480, tony@schaller.net
  • OS/Application focus: Debian Linux, Nginx, Gitlab, NodeJS, Strapi, Gatsby, Express, NextJs, MySQL, rsyslog, rdiff-backup
  • The existing, informal application deployment process was redesigned to make it possible to scale quickly to add new applications, environments and servers. This included unifying the directory structure for all applications, separating of read and write role users for security, using rsyslog to feed file logs to journald, and using diff-based backups at deployment time for easy reversion to older deployments.
  • All existing application deployment processes (Strapi, Gatsby, Express), most of which were manual, were migrated to gitlab and this unified structure, and a new application was added (NextJS).
  • Development and staging envorinments were added to the production (the only existing environment), bring the total number of application servers quickly from 2 to 7.
  • Extensive multi-way failover was designed and configured between all application servers across all applications using CloudFlare and Nginx. This makes deployments seemless and limits potentional downtime to a few seconds.
