get_url - Downloads files from HTTP, HTTPS, or FTP to node
Synopsis
- Downloads files from HTTP, HTTPS, or FTP to the remote server. The remote server must have direct access to the remote resource.
- By default, if an environment variable
<protocol>_proxy
is set on the target host, requests will be sent through that proxy. This behaviour can be overridden by setting a variable for this task (see setting the environment), or by using the use_proxy option. - HTTP redirects can redirect from HTTP to HTTPS so you should be sure that your proxy environment for both protocols is correct.
- From Ansible 2.4 when run with
--check
, it will do a HEAD request to validate the URL but will not download the entire file or verify it against hashes. - For Windows targets, use the win_get_url module instead.
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
attributes (added in 2.3) | Default: None | Attributes the file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr. aliases: attr |
backup (added in 2.1) |
| Create a backup file including the timestamp information so you can get the original file back if you somehow clobbered it incorrectly. |
checksum (added in 2.0) | Default: | If a 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. Format: <algorithm>:<checksum>, e.g. checksum="sha256:D98291AC[...]B6DC7B97" If you worry about portability, only the sha1 algorithm is available on all platforms and python versions. The third party hashlib library can be installed for access to additional algorithms. Additionally, if a checksum is passed to this parameter, and the file exist under the dest location, the destination_checksum would be calculated, and if checksum equals destination_checksum, the file download would be skipped (unless force is true). |
client_cert (added in 2.4) | PEM formatted certificate chain file to be used for SSL client authentication. This file can also include the key as well, and if the key is included, client_key is not required. | |
client_key (added in 2.4) | PEM formatted file that contains your private key to be used for SSL client authentication. If client_cert contains both the certificate and key, this option is not required. | |
dest required | Absolute path of where to download the file to. If dest is a directory, either the server provided filename or, if none provided, the base name of the URL on the remote server will be used. If a directory, force has no effect.If dest is a directory, the file will always be downloaded (regardless of the force option), but replaced only if the contents changed.. | |
force |
| If yes and dest is not a directory, will download the file every time and replace the file if the contents change. If no , the file will only be downloaded if the destination does not exist. Generally should be yes only for small local files.Prior to 0.6, this module behaved as if yes was the default.aliases: thirsty |
force_basic_auth (added in 2.0) |
| httplib2, the library used by the uri module only sends authentication information when a webservice responds to an initial request with a 401 status. Since some basic auth services do not properly send a 401, logins will fail. This option forces the sending of the Basic authentication header upon initial request. |
group | Default: None | Name of the group that should own the file/directory, as would be fed to chown. |
headers (added in 2.0) | Add custom HTTP headers to a request in the format "key:value,key:value". | |
mode | Default: None | Mode the file or directory should be. For those used to /usr/bin/chmod remember that modes are actually octal numbers (like 0644 or 01777 ). Leaving off the leading zero will likely have unexpected results. As of version 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r ). |
others | all arguments accepted by the file module also work here | |
owner | Default: None | Name of the user that should own the file/directory, as would be fed to chown. |
selevel | Default: s0 | Level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range . _default feature works as for seuser. |
serole | Default: None | Role part of SELinux file context, _default feature works as for seuser. |
setype | Default: None | Type part of SELinux file context, _default feature works as for seuser. |
seuser | Default: None | User part of SELinux file context. Will default to system policy, if applicable. If set to _default , it will use the user portion of the policy if available. |
sha256sum (added in 1.3) | Default: | If a SHA-256 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. Use checksum instead. |
timeout (added in 1.8) | Default: 10 | Timeout in seconds for URL request. |
tmp_dest (added in 2.1) | Absolute path of where temporary file is downloaded to. When run on Ansible 2.5 or greater, path defaults to ansible's remote_tmp setting When run on Ansible prior to 2.5, it defaults to TMPDIR , TEMP or TMP env variables or a platform specific value. | |
unsafe_writes (added in 2.2) |
| Normally this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, sometimes systems are configured or just broken in ways that prevent this. One example are docker mounted files, they cannot be updated atomically and can only be done in an unsafe manner. This boolean option allows ansible to fall back to unsafe methods of updating files for those cases in which you do not have any other choice. Be aware that this is subject to race conditions and can lead to data corruption. |
url required | HTTP, HTTPS, or FTP URL in the form (http|https|ftp)://[user[:pass]]@host.domain[:port]/path | |
url_password (added in 1.6) | The password for use in HTTP basic authentication. If the url_username parameter is not specified, the url_password parameter will not be used. | |
url_username (added in 1.6) | The username for use in HTTP basic authentication. This parameter can be used without url_password for sites that allow empty passwords. | |
use_proxy |
| if no , it will not use a proxy, even if one is defined in an environment variable on the target hosts. |
validate_certs |
| If no , SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. |
Notes
Note
- For Windows targets, use the win_get_url module instead.
