converge

converge is an an easy and powerful configuration management tool that can scale from managing Raspberry Pi devices and developer desktops all the way up to deploying complex applications onto clusters of servers.

3. http://aster.is converge
4. converge configuration made easy
5. 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
6. 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
7. 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" } }
8. easy to share embed converge file with source code converge publish via http, s3 wrap existing scripts
9. 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.)
10. powerful graph engine
11. graph benefits automatic dependency generation pinpoint failures parallel execution converge
12. create graphs visualize install tasks converge converge graph converge.hcl replace curl | bash -
13. D O C K E R E L K D E M O integrated with terraform spin up clusters with one command

15. api first via all communication (including cli) is via grpc devices look like another microservice http/2 bi-directional streaming converge
16. I N S TA L L S converge Confirming patches and security configuration IoT Devices Autoscaling groups
17. verify modules via pgp add trusted keys and verify modules converge converge key trust samples/pubkey.gpg converge plan —verify-modules samples/ basic.hcl
18. examples
19. 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
20. 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`}}" } } }
21. 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"] }
22. internals
23. parallel execution converge
24. converge docker running? deferred evaluation start docker.container lookup docker.container.port
25. summary easy & powerful scales down made for modern infrastructure converge
