There are multiple methods in Ansible by which you can delete a particular file or directory, delete all files in a directory, delete files using regex etc. The safe way is to use the Ansible file module. You can also use the shell module to achieve the task.
But it is not idempotent and hence re-execution will throw errors. You can use the Ansible file module to delete a particular file safely. The module provides the parameter state with option absent to remove the file from the target machine.
This can also be used to delete directories or symlinks. The following example will remove the delete. Generally should be yes only for small local files. Since some basic auth services do not properly send a , logins will fail. The "key:value,key:value" string format is deprecated and has been removed in version 2.
You must either add a leading zero so that Ansible's YAML parser knows it is an octal number like or or quote it like '' or '' so Ansible receives a string and can do its own conversion from string into number.
Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results.
As of Ansible 1. If mode is not specified and the destination file does not exist, the default umask on the system will be used when setting the mode for the newly created file. If mode is not specified and the destination file does exist, the mode of the existing file will be used.
Specifying mode is the best way to ensure files are created with the correct permissions. See CVE for further details. If a SHA checksum is passed to this parameter, the digest of the destination file will be calculated after it is downloaded to ensure its integrity and verify that the transfer completed successfully.
This option is deprecated and will be removed in version 2. Use option checksum instead. When run on Ansible prior to 2. Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file.
By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this.
One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. SRC represents source file path or path of the file which we are going to copy. DEST represents the destination path on the remote server. In this example we are copying devops. With ansible copy we can copy multiple files. In this example we are copying multiple files from ansible master machine to remote server.
But in this example we are copying all the files from devops directory to remote server rundeck directory. In this example we are copying three 3 files from different locations to different locations in remote server. Download the nginx configuration file 'nginx. And the default fetch module will include the directory structures. Download from the Remote Machine to Local ansible-node without directory structures by adding the 'flat' option.
Now we're going to edit files using Ansible modules. There are some modules that you must know for editing files using the Ansible, such as blockinfile, lineinfile, and replace.
The lineinfile is for the single line, and the replace module can be used to replace string. And the default setup will insert the new configuration to the bottom of lines.
Or if you want to insert to the specific line, you can use the marker option and follow by 'insertafter' or 'insertbefore' and Regex, or you can use both. Now we're going to replace a string using the 'replace' module. The replace module required the regular expression as backend-reference to replace kind of strings.
The replace module can be used to uncomment the configuration on the Linux system.
