The Multicore Software Development Kit MCSDK provides foundational software for TI KeyStone II device platforms. It encapsulates a collection of software. Dynamic Inventory Ansible Documentation. Often a user of a configuration management system will want to keep inventory. Ansible provides a basic text based system as described in. Inventory but what if you want to use something else Frequent examples include pulling inventory from a cloud provider, LDAP, Cobbler. CMDB software. Ansible easily supports all of these options via an external inventory system. The contribinventory directory contains some of these already including options for EC2Eucalyptus, Rackspace Cloud, and Open. Stack, examples of some of which will be detailed below. D21ZUh' alt='How To Install Kernel Sources Bsd' title='How To Install Kernel Sources Bsd' />Ansible Tower also provides a database to store inventory results that is both web and REST Accessible. Tower syncs with all Ansible dynamic inventory sources you might be using, and also includes a graphical inventory editor. By having a database record of all of your hosts, its easy to correlate past event history and see which ones have had failures on their last playbook runs. For information about writing your own dynamic inventory source, see Developing Dynamic Inventory Sources. It is expected that many Ansible users with a reasonable amount of physical hardware may also be Cobbler users. Cobbler was originally written by Michael De. Haan and is now led by James Cammarata, who also works for Ansible, Inc. While primarily used to kickoff OS installations and manage DHCP and DNS, Cobbler has a generic. CMDB by some admins. To tie Ansibles inventory to Cobbler optional, copy this script to etcansible and chmodx the file. Ansible and youll need to use Ansibles i command line option e. This particular script will communicate with Cobbler using Cobblers XMLRPC API. Also a cobbler. ini file should be added to etcansible so Ansible knows where the Cobbler server is and some cache improvements can be used. For example cobbler Set Cobblers hostname or IP addresshost http 1. API calls to Cobbler can be slow. For this reason, we cache the results of an API call. Set this to the path you want cache files to be written to. Two files will be written to this directory ansible cobbler. The number of seconds a cache file is considered valid. After this many seconds, a new API call will be made, and the cache file will be updated. First test the script by running etcansiblecobbler. You should see some JSON data output, but it may not have anything in it just yet. Lets explore what this does. In Cobbler, assume a scenario somewhat like the following cobbler profile add namewebserver distroCent. OS6 x. 866. 4cobbler profile edit namewebserver mgmt classeswebserver ksmetaa2 b3cobbler system edit namefoo dns namefoo. In the example above, the system foo. Since Ansible uses SSH, well try to contact system foo over foo. Similarly, if you try ansible foo it wouldnt find the system. DNS name starts with foo. The script doesnt just provide host and group info. In addition, as a bonus, when the setup module is run which happens automatically when using playbooks, the variables a, b, and c will all be auto populated in the templates file srvmotd. Welcome, I am templated with a value of aa, bb, and ccWhich could be executed just like this ansible webserver m setupansible webserver m template a srctmpmotd. Note. The name webserver came from Cobbler, as did the variables for. American Laser Games Pc here. You can still pass in your own variables like. Ansible, but variables from the external inventory script. So, with the template above motd. Welcome, I am templated with a value of a2, b3, and c4. And on system bar bar. Welcome, I am templated with a value of a2, b3, and c5. And technically, though there is no major good reason to do it, this also works too ansible webserver m shell a echo aSo in other words, you can use those variables in argumentsactions as well. If you use Amazon Web Services EC2, maintaining an inventory file might not be the best approach, because hosts may come and go over time, be managed by external applications, or you might even be using AWS autoscaling. For this reason, you can use the EC2 external inventory script. You can use this script in one of two ways. The easiest is to use Ansibles i command line option and specify the path to the script after. The second option is to copy the script to etcansiblehosts and chmod x it. You will also need to copy the ec. Then you can run ansible as you would normally. To successfully make an API call to AWS, you will need to configure Boto the Python interface to AWS. There are a variety of methods available, but the simplest is just to export two environment variables export AWSACCESSKEYIDAK1. AWSSECRETACCESSKEYabc. You can test the script by itself to make sure your config is correct cd contribinventory. After a few moments, you should see your entire EC2 inventory across all regions in JSON. If you use Boto profiles to manage multiple AWS accounts, you can pass profile. PROFILE name to the ec. An example profile might be profile devawsaccesskeyid lt dev access key awssecretaccesskey lt dev secret key profile prodawsaccesskeyid lt prod access key awssecretaccesskey lt prod secret key You can then run ec. You can also use the AWSPROFILE variable for example AWSPROFILEprodansible playbook iec. Since each region requires its own API call, if you are only using a small set of regions, you can edit the ec. There are other config options in ec. By default, the ec. Amazon cloud services, but you can comment out any features that arent applicable. For example, if you dont have RDS or elasticache, you can set them to Falseec. To exclude RDS instances from the inventory, uncomment and set to False. False To exclude Elasti. Cache instances from the inventory, uncomment and set to False. False. At their heart, inventory files are simply a mapping from some name to a destination address. The default ec. 2. Ansible from outside EC2 from your laptop for example and this is not the most efficient way to manage EC2. If you are running Ansible from within EC2, internal DNS names and IP addresses may make more sense than public DNS names. In this case, you can modify the destinationvariable in ec. DNS name of an instance. This is particularly important when running Ansible within a private subnet inside a VPC, where the only way to access an instance is via its private IP address. For VPC instances, vpcdestinationvariable in ec. The EC2 external inventory provides mappings to instances from several groups Global. All instances are in group ec. Instance IDThese are groups of one since instance IDs are unique. Region. A group of all instances in an AWS region. Availability Zone. A group of all instances in an availability zone. Security Group. Instances belong to one or more security groups. A group is created for each security group, with all characters except alphanumerics, converted to underscores. Steps To Install Ns2 In Fedora 15 Dvd. Each group is prefixed by securitygroup. Currently, dashes are also converted to underscores. You can change using the replacedashingroups setting in ec. PetesFancyGroup. Tags. Each instance can have a variety of keyvalue pairs associated with it called Tags. The most common tag key is Name, though anything is possible. Each keyvalue pair is its own group of instances, again with special characters converted to underscores, in the format tagKEYVALUE. NameWeb can be used as is.
