Release Date

2016-12-29 0.5.0

Features

This release includes new modules and general usability enhancements for users
and module authors.

Remove Vendoring

For converge 0.5.0 we have removed the vendor directory from the converge
repository. glide install will now run as part of the build process to ensure
all dependencies are installed.

Demo Applications

A demo of using converge for a kubernetes deployment was added in 524.

Module Improvements

File Fetch

File download and verification support has been added via #543.

file.fetch "consul.zip" {
  source      = "https://releases.hashicorp.com/consul/0.6.4/consul_0.6.4_linux_amd64.zip"
  destination = "/tmp/consul.zip"
  hash_type   = "sha256"
  hash        = "abdf0e1856292468e2c9971420d73b805e93888e006c76324ae39416edcf0627"
}

File Owner

File ownership can now be changed with the file.owner module added via #549.

file.owner "owner-test" {
  destination = "dir"
  group       = "root"
  user        = "root"
  verbose     = true
  recursive   = true
}

Usability Enhancements

Better Cascading Error Output

Modules with failing dependencies are now summarized at the end of a run via 516.

root/task.directory:
 Error: exec: "blah": executable file not found in $PATH
 Messages:
 Has Changes: no
 Changes: No changes

Errors:
 * root/task.directory: exec: "blah": executable file not found in $PATH

Failed due to failing dependency:
 * root/task.key: error in dependency "root/task.directory"
 * root/task.csr: error in dependency "root/task.key"
 * root/task.crt: error in dependency "root/task.csr"

Summary: 1 errors, 0 changes, 3 dependency errors

Resource Name Restrictions

As of 535 resource names are
now restricted to strings consisting of letters, numbers, dots . and dashes
-. Unicode letter characters are supported.

Diff Output During Application

As of 533 diff outputs
should be displayed when running apply.

Engine Improvements

Module API Enhancements

The module authoring API has been updated to make it easier to develop modules.

Explicit Value Exports

As of 533 the export and
re-export-as tags are supported for resource.Resource types in modules.
These tags are now required to make fields available for lookup.

New Module Author Idioms

As of 533 resource types in
modules should not embed resource.Status. The Check and Apply functions
should no longer return the resource itself but instead a generated task status.

Bug Fixes

Converge 0.5.0 introduces a multitiude of bugfixes and stability improvements.
Please refer to the changelog for
a detailed report.

0.3.0

@BrianHicks BrianHicks released this Oct 27, 2016 · 517 commits to master since this release

This is the final release for Converge 0.3.0. Please refer to the release notes (also included below) for changes and the 0.3.0 documentation for usage.

Features

This release includes a number of significant improvements to the core engine including conditionals,
wait queries, sequential task groups, and the ability to use lists and maps in parameters. The internal API has also been simplified to make it easier for programmers to create new modules.

Module Improvements

RPM Resource

RPM package install/uninstall support has been added via #373.

rpm.package "mc" {
    name  = "mc"
    state = "present"
}

User and group

Linux user groups can now be modified via #279

wait.query and wait.port

Converge now supports waiting for a task to complete or port #334.
Users can create a dependency for a port to be open or a condition to be met.

Below is an example of waiting for a port to be open using the wait.port resource:

wait.port "8080" {
  host         = "localhost"
  port         = 8080
  interval     = "1s"
  max_retry    = 10
  grace_period = "2s"
}

The following shows using wait.query to wait using a task:

wait.query "service-health" {
  check        = "nc -z localhost 8080"
  interval     = "1s"
  max_retry    = 10
  grace_period = "1s"
}

Wait is documented at: wait.port and wait.query.

Engine Improvements

Conditional Support

Support for conditionals via #362.

In the following example, the contents of file greetings.txt depend on the value of
the lang parameter:

param "lang" {
  default = ""
}

switch "test-switch" {
  case "eq `spanish` `{{param `lang`}}`" "spanish" {
    file.content "foo-file" {
      destination = "greeting.txt"
      content     = "hola\n"
    }
  }

  case "eq `french` `{{param `lang`}}`" "french" {
    file.content "foo-file" {
      destination = "greeting.txt"
      content     = "salut\n"
    }
  }

Task Groups

Tasks can be assigned to a group to force multiple tasks to run
one at a time instead of in parallel. When a node is added to a task
group the engine creates a dependency on another node in the group.

Please note that task groups are not supported in conditionals in 0.3.

#392

For example, apt package installs cannot run in parallel. In the following example
each task with the apt lock is run sequentially.

task "install-jq" {
  check = "dpkg -s jq >/dev/null 2>&1"
  apply = "apt-get update 2>&1 > /dev/null && apt-get -y install jq"
  group  = "apt"
}

task "install-build-essential" {
  check = "dpkg -s build-essential >/dev/null 2>&1"
  apply = "apt-get update 2>&1 > /dev/null && apt-get -y install build-essential"
  group  = "apt"
}

Enhanced Parameter Values

bool, list, and map types have been added to parameters via #340.

See values

Output Improvements

Rendered graphs have been cleaned and arrows now indicate the order of tasks #387.

Text output for changes is now aligned via #317.

Installation Script

An installation script (install-converge.sh) has been added that downloads the correct
binary of converge after detecting the underlying Operating System and Processor.

This can be used to install converge during system boot.

For example, the terraform provisioner
uses this script download the latest release of converge before configuring a node.

Bug Fixes

Please refer to the changelog for
a detailed report.

Examples/Documentation

A Docker image was created in #372 to speed up Wercker builds and automated tests.

Documentation was updated in #371 so that links like
converge.aster.is/0.2.0 will resolve documentation for that version.

The elasticsearch example has been updated to use new features in 0.3.0 #419
