README

---

Werf (previously known as Dapp) is made to implement and support Continuous Integration and Continuous Delivery (CI/CD).

It helps DevOps engineers generate and deploy images by linking together:

• application code (with Git support),
• infrastructure code (with Ansible or shell scripts), and
• platform as a service (Kubernetes).

Werf simplifies development of build scripts, reduces commit build time and automates deployment. It is designed to make engineer's work fast end efficient.

Install Werf

Way 1 (recommended): using Multiwerf

Multiwerf is a version manager for Werf, which:

• downloads werf binary builds;
• manages multiple versions of binaries installed on a single host, that can be used at the same time;
• automatically updates werf binary (can be disabled).

mkdir ~/bin
cd ~/bin
curl -L https://raw.githubusercontent.com/flant/multiwerf/master/install.sh | bash
source <(multiwerf use 1.0 alpha)
