converge configuration made easy 

D E V E LO P E R D E S K TO P converge ad-hoc solutions (npm, brew, etc.) DevOps tools currently not used Need to install lots of tools & run docker containers 

easy for developers converge plan build-env.hcl converge apply —param masters=3 etcd.hcl 11mb binary (cli + modules + agent) converge start with a single file 

simple configuration converge param "image-tag" { default = "1.10-alpine" } docker.image "nginx" { name = "nginx" tag = "{{param `image-tag`}}" timeout = "60s" } docker.container "nginx" { name = "nginx-server" image = "nginx:{{lookup `docker.image.nginx.Tag`}}" force = "true" ports = ["80"] env { "CONVERGE" = "AWESOME" } } 

easy to share embed converge file with source code converge publish via http, s3 wrap existing scripts 

C O N F I G U R I N G S E RV E R S converge Integrate Server Configuration With Cloud Resources Configuration as a Microservice Deploy and Manage Container Stacks (Kubernetes, Swarm, etc.) 

powerful graph engine 

graph benefits automatic dependency generation pinpoint failures parallel execution converge 

create graphs visualize install tasks converge converge graph converge.hcl replace curl | bash - 

D O C K E R E L K D E M O integrated with terraform spin up clusters with one command

api first via all communication (including cli) is via grpc devices look like another microservice http/2 bi-directional streaming converge 

I N S TA L L S converge Confirming patches and security configuration IoT Devices Autoscaling groups 

verify modules via pgp add trusted keys and verify modules converge converge key trust samples/pubkey.gpg converge plan —verify-modules samples/ basic.hcl 

examples 

converge file.directory "data" { destination = "/var/lib/influxdb" } module "docker/container.hcl" "influx" { params { name = "influxdb" image = "influxdb" tag = "1.0.0-rc1" ports = ["8086:8086"] volumes = ["/var/lib/influxdb:/var/lib/influxdb"] } depends = ["file.directory.data"] } wait for a directory & pass parameters into modules 

conditional task execution converge switch "deps" { case "eq `{{platform.LinuxDistribution}}` `centos`" "centos" { package.rpm "deps" { name = "coreutils gcc git graphviz make tar unzip which" state = "present" } } case "eq `{{platform.LinuxDistribution}}` `debian`" "debian" { task "package-install" { check = "dpkg -s {{param `name`}} >/dev/null 2>&1" apply = "apt-get -y install {{param `packages`}}" } } } 

wait for a file to be present converge wait.query "unzip-check" { check = "unzip -v" interval = "2s" max_retry = 60 grace_period = "3s" interpreter = "/bin/bash" } task "protoc-extract" { check = "[[ -f /usr/local/bin/protoc ]]" apply = "unzip /tmp/protoc-{{param `protoc-version`}}-linux- x86_64.zip" dir = "/usr/local" interpreter = "/bin/bash" depends = ["wait.query.unzip-check"] } 

internals 

parallel execution converge 

converge docker running? deferred evaluation start docker.container lookup docker.container.port 

summary easy & powerful scales down made for modern infrastructure converge
