The App Engine SDK includes a command for uploading application files. As with the rest of the SDK, appcfg.py
runs on any computer with Python 2.5.
To upload application files, run the appcfg.py
command with the update
action and the name of your application's root directory. The root directory should contain the app.yaml file for the application.
appcfg.py update myapp/
appcfg.py
gets the application ID from the app.yaml
file, and prompts you for the email address and password of your Google account. After successfully signing in with your account, appcfg.py
stores a "cookie" so that it does not need to prompt for a password on subsequent attempts.
You can specify the email address on the command line using the --email
option. You cannot specify the password as a command line option.
appcfg.py --email=Albert.Johnson@example.com update myapp/
The appcfg.py
command takes a set of options, an action, and arguments for the action.
The following actions are available:
appcfg.py [options] update <app-directory>
Uploads files for an application given the application's root directory. The application ID and version are taken from the app.yaml
file in the app directory.
appcfg.py [options] rollback <app-directory>
Undo a partially completed update for the given application. You can use this if an update was interrupted, and the command is reporting that the application cannot be updated due to a lock.
appcfg.py [options] vacuum_indexes <app-directory>
Delete unused datastore indexes in App Engine. If an index definition is removed from index.yaml, the index is not deleted automatically when the application is uploaded because it may be in use by another version of the application. Run this action when all old indexes are no longer needed.
appcfg.py [options] request_logs <app-directory> <output-file>
Retrieve log data for the application running on App Engine. output-file
is the name of the file to create, replace or append (if the --append
flag is set). If output-file
is a hyphen (-
), the log data is printed to the console. The following options apply to request_logs
:
--num_days=...
The number of days of log data to retrieve, ending on the current date at midnight UTC. A value of 0 retrieves all available logs. If --append
is given, then the default is 0, otherwise the default is 1.
--severity=...
The minimum log level for the log messages to retrieve. The value is a number corresponding to the log level: 4 for CRITICAL, 3 for ERROR, 2 for WARNING, 1 for INFO, 0 for DEBUG. All messages at the given log level and above will be retrieved. Default is 1 (INFO).
--append
Append the fetched data to the output file, starting with the first log line not already present in the file. Running this command once a day with --append
results in a file containing all log data.
The default is to overwrite the output file. Does not apply if output-file
is -
(printing to the console).
appcfg.py help <action>
Print a help message about the given action, then quit.
The appcfg.py
command accepts the following options for all actions:
--quiet
Do not print messages when successful.
--verbose
Print messages about what the command is doing.
--noisy
Print many messages about what the command is doing. This is mostly useful when working with the App Engine team to troubleshoot an upload issue.
--email=...
The email address of the Google account of an administrator for the application, for actions that require signing in. If omitted and no cookie is stored from a previous use of the command, the command will prompt for this value.
--server=...
The App Engine server hostname. The default is appengine.google.com
.
--host=...
The hostname of the local machine for use with remote procedure calls.
--no_cookies
Do not store the administrator sign-in credentials as a cookie; prompt for a password every time.
--force
Force deletion of unused indexes. By default, uploading an app does not delete unused indexes from the server, even if they do not appear in the index.yaml
file.
--max_size=...
A maximum size of files to upload, as a number of bytes. Files larger than this size will not be uploaded. The default is 1048576
. The server currently enforces a maximum file size of 1,048,576 bytes, so increasing this value will not have any effect.
If you are running appcfg.py
behind an HTTP proxy, you must tell appcfy.py
the name of the proxy. To set an HTTP proxy for appcfg.py
, set the http_proxy
environment variable. For example, in the bash shell:
export http_proxy="http://cache.mycompany.com:3128" appcfg.py update myapp
