ansible.builtin.get_url module – Downloads files from HTTP, HTTPS, or FTP to node

Note

This module is part of ansible-core and included in all Ansible installations. In most cases, you can use the short module name get_url even without specifying the collections: keyword. However, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 0.6: of ansible.builtin

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 and will report incorrect changed status.

• For Windows targets, use the ansible.windows.win_get_url module instead.

Parameters

Parameter	Comments
attributes aliases: attr string added in 2.3 of ansible.builtin	The attributes the resulting filesystem object 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. The = operator is assumed as default, otherwise + or - operators need to be included in the string.
backup boolean added in 2.1 of ansible.builtin	Create a backup file including the timestamp information so you can get the original file back if you somehow clobbered it incorrectly. Choices: no ← (default) yes
checksum string added in 2.0 of ansible.builtin	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|url>, e.g. checksum=”sha256:D98291AC[…]B6DC7B97”, checksum=”sha256:http://example.com/path/sha256sum.txt” 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). If the checksum does not equal destination_checksum, the destination file is deleted. Default: “”
client_cert path added in 2.4 of ansible.builtin	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 path added in 2.4 of ansible.builtin	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 path / 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 and checksum option), but replaced only if the contents changed.
force boolean added in 0.7 of ansible.builtin	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. Choices: no ← (default) yes
force_basic_auth boolean added in 2.0 of ansible.builtin	Force the sending of the Basic authentication header upon initial request. 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. Choices: no ← (default) yes
group string	Name of the group that should own the filesystem object, as would be fed to chown.
headers dictionary added in 2.0 of ansible.builtin	Add custom HTTP headers to a request in hash/dict format. The hash/dict format was added in Ansible 2.6. Previous versions used a "key:value,key:value" string format. The "key:value,key:value" string format is deprecated and has been removed in version 2.10.
http_agent string	Header to identify as, generally appears in web server logs. Default: “ansible-httpget”
mode raw	The permissions the resulting filesystem object should have. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible’s YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') 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 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r). If mode is not specified and the destination filesystem object does not exist, the default umask on the system will be used when setting the mode for the newly created filesystem object. If mode is not specified and the destination filesystem object does exist, the mode of the existing filesystem object will be used. Specifying mode is the best way to ensure filesystem objects are created with the correct permissions. See CVE-2020-1736 for further details.
owner string	Name of the user that should own the filesystem object, as would be fed to chown.
selevel string	The level part of the SELinux filesystem object context. This is the MLS/MCS attribute, sometimes known as the range. When set to _default, it will use the level portion of the policy if available.
serole string	The role part of the SELinux filesystem object context. When set to _default, it will use the role portion of the policy if available.
setype string	The type part of the SELinux filesystem object context. When set to _default, it will use the type portion of the policy if available.
seuser string	The user part of the SELinux filesystem object context. By default it uses the system policy, where applicable. When set to _default, it will use the user portion of the policy if available.
sha256sum string added in 1.3 of ansible.builtin	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 and will be removed in version 2.14. Use option checksum instead. Default: “”
timeout integer added in 1.8 of ansible.builtin	Timeout in seconds for URL request. Default: 10
tmp_dest path added in 2.1 of ansible.builtin	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. https://docs.python.org/3/library/tempfile.html#tempfile.tempdir
unredirected_headers list / elements=string added in 2.12 of ansible.builtin	A list of header names that will not be sent on subsequent redirected requests. This list is case insensitive. By default all headers will be redirected. In some cases it may be beneficial to list headers such as Authorization here to avoid potential credential exposure. Default: []
unsafe_writes boolean added in 2.2 of ansible.builtin	Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target filesystem object. By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target filesystem objects, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted filesystem objects, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. This option allows Ansible to fall back to unsafe methods of updating filesystem objects when atomic operations fail (however, it doesn’t force Ansible to perform unsafe writes). IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption. Choices: no ← (default) yes
url string / required	HTTP, HTTPS, or FTP URL in the form (http|https|ftp)://[user[:pass]]@host.domain[:port]/path
url_password aliases: password string added in 1.6 of ansible.builtin	The password for use in HTTP basic authentication. If the url_username parameter is not specified, the url_password parameter will not be used. Since version 2.8 you can also use the ‘password’ alias for this option.
url_username aliases: username string added in 1.6 of ansible.builtin	The username for use in HTTP basic authentication. This parameter can be used without url_password for sites that allow empty passwords. Since version 2.8 you can also use the username alias for this option.
use_gssapi boolean added in 2.11 of ansible.builtin	Use GSSAPI to perform the authentication, typically this is for Kerberos or Kerberos through Negotiate authentication. Requires the Python library gssapi to be installed. Credentials for GSSAPI can be specified with url_username/url_password or with the GSSAPI env var KRB5CCNAME that specified a custom Kerberos credential cache. NTLM authentication is not supported even if the GSSAPI mech for NTLM has been installed. Choices: no ← (default) yes
use_proxy boolean	if no, it will not use a proxy, even if one is defined in an environment variable on the target hosts. Choices: no yes ← (default)
validate_certs boolean	If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. Choices: no yes ← (default)

Attributes

Attribute	Support	Description
check_mode	Support: partial the changed status will reflect comparison to an empty source file	Can run in check_mode and return changed status prediction without modifying target
diff_mode	Support: none	Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode
platform	Platform: posix	Target OS/families that can be operated against
