A powerful and easy-to-use configuration management system.
2017-03-02 0.6.0
With this release, Converge no longer supports freebsd and solaris.
This release includes new systemd and unarchive capabilities, improvements to the user resource, and generators for man pages and bash autocomplete.
Support for controlling systemd services has been added via #602.
systemd.unit.state "ssh" {
unit = "ssh.service"
state = "running"
}
Managing several archive formats such as zip and tar.gz is available through unarchive support in #592.
unarchive "consul.zip" {
source = "/tmp/consul.zip"
destination = "/tmp/consul"
}
A user can now be enabled or disabled with the addition of #581.
Additionally, there are updates to the diffs presented for user with #584 and #588.
A new helper method has been added to for use with resource.Status. RaiseLevelForDiffs will raise the status level to StatusWillChange if any differences exist via #587.
Generators for man pages and bash autocompletion have been added via #571.
See the Converge changelog for additional details on the 0.6.0 release.
We provide support via the Converge Slack and through GitHub Issues.

This is the final release for Converge 0.4.0. Please refer to the release notes (also included below) for changes and the 0.4.0 documentation for usage.
This release includes a number of new and improved modules, several bugfixes in the core engine, and enhancements to the internal API to ease the module creation process.
LVM volume creation has been added for Linux based systems via #184.
lvm.volumegroup "vg-test" {
name = "test"
devices = ["/dev/sda","/dev/sdb"]
}
lvm.logicalvolume "lv-test" {

}
filesystem "mnt-me" {
device = "/dev/mapper/test-test"
mount = "/mnt"
fstype = "ext3"
depends = ["lvm.logicalvolume.lv-test"]
}
Apt package installation has been added via #461.
package.apt "mc" {
group = "apt"
name = "mc"
state = "present"
}
Support for docker volumes has been added via #453
docker.volume "elasticsearch" {
name = "elasticsearch"
labels {
environment = "test"
}
state = "present"
force = true
}
Support for docker networking has been added via #477
docker.network "test-network" {
name = "test-network"
state = "present"
force = true
labels {
environment = "test"
}
options {
"com.docker.network.bridge.enable_icc" = "true"
}
internal = false
ipv6 = false
ipam_driver = "default"
ipam_config {
subnet = "192.168.129.0/24"
gateway = "192.168.129.1"
aux_addresses {
router = "192.168.129.40"
printer = "192.168.129.41"
}
}
}
Users can now be modified thanks to #434. This change also adds several new fields to the user module which can be used during user creation or modification including:
create_home to create a home directory for a usermove_dir to move contents of a users home directory if it changesskel_dir to specify a skeleton directory to use when creating a userThe module authoring API has been updated to make it easier to develop modules.
Resources now support the nonempty struct tag as demonstrated by this snippet
from the user module:
type Preparer struct {
// Username is the user login name.
Username string `hcl:"username" required:"true" nonempty:"true"`
when nonempty:"true" is set, an error will be returned if the user sets the
value of a field to the zero value for it's type.
Resource structs may now use time.Duration as a field type. Duration strings
will be parsed as a time duration automatically; numeric values will be treated
as a time in seconds.

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.
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.
RPM package install/uninstall support has been added via #373.
rpm.package "mc" {
name = "mc"
state = "present"
}
Linux user groups can now be modified via #279
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.
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"
}
}
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.
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"
}
bool, list, and map types have been added to parameters via #340.
See values
Rendered graphs have been cleaned and arrows now indicate the order of tasks #387.
Text output for changes is now aligned via #317.
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.
Please refer to the changelog for a detailed report.
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
