i would like cloud-init to not use 50-cloud-init.yaml. I have prepared my own file.
Do you know how to do this
You can add
network:
config: disabled
to /etc/cloud/cloud.cfg or a file in /etc/cloud/cloud.cfg.d.
Another option is to add
network-config=disabled
to the kernel command line.
While the network config yaml technically works as userdata, the network configuration will have already been written out before userdata is read.
One other option is to write your netplan configuration into /etc/netplan/99-some-name.yaml. If you have configuration there that overlaps with what is in 50-cloud-init.yaml, your configuration will override what is in the default configuration.
See https://cloudinit.readthedocs.io/en/latest/topics/network-config.html#disabling-network-configuration .

Is there a way to encrypt the airflow config file sql_alchemy_conn string , the password shown in example is plaintext . What options are there to secure it. Also if the password has special chars how it must be escaped in the config file
Trying to install airflow using airflow role.
# See: https://www.sqlalchemy.org/
sql_alchemy_conn:
value: "postgresql+psycopg2://pgclusteradm#servername:PLAINTEXTPASSWORD#server.postgres.database.azure.com/airflow2"
Way to encrypt password, couldn't find how to encrypt this.
You can provide the database URI through environment variables instead of the config file. This doesn't encrypt it or necessarily make it more secure, but it at least isn't plainly sitting in a permanent file.
In your airflow.cfg you can put a placeholder:
[core]
...
sql_alchemy_conn = override_me
...
Then set AIRFLOW__CORE__SQL_ALCHEMY_CONN=postgresql+psycopg2://... in an environment variable when you bring up Airflow components. This way of setting and overriding configuration options through environment variables is detailed in the docs, but the basic format is AIRFLOW__{SECTION}__{KEY}=<value>.
There are 2 ways of securing this as mentioned in docs:
1) Environment Variable:
You can override the setting in airflow.cfg by setting the following environment variable:
AIRFLOW__CORE__SQL_ALCHEMY_CONN=my_conn_string
This way you can keep the setting in airflow.cfg as empty so no one can view the password.
2) Get string by running command:
You can also derive the connection string at run time by appending _cmd to the key like this:
[core]
sql_alchemy_conn_cmd = bash_command_to_run
I'm trying to send multiple nginx logs to loggly...
Config file: /etc/rsyslog.d/21-nginx.conf
$ModLoad imfile
#$InputFilePollInterval 10
$InputFileMode inotify
$WorkDirectory /var/spool/rsyslog
$PrivDropToGroup adm
# nginx access file:
$InputFileName /var/log/nginx/*access.log
$InputFileTag nginx-access:
$InputFileStateFile stat-nginx-access
$InputFileSeverity info
$InputFilePersistStateInterval 20000
$InputRunFileMonitor
# other stuff continues......
after restart i get this error in log syslog:
imfile: The to-be-monitored file "/var/log/nginx/*access.log" contains wildcards. This is not supported in polling mode. [v8.16.0 try http://www.rsyslog.com/e/2420 ]
activation of module imfile failed [v8.16.0 try http://www.rsyslog.com/e/-3 ]
did i make something wrong?
Are there other places in your rsyslog configuration where the file mode is changed to pulling or the file poll interval is active? The problem with using this kind of legacy syntax is that all the configuration is loaded globally, so things in other configuration files can interact. You might consider using the new action syntax so that the inotify mode is applied to the specific source. You can see an example of it here http://www.rsyslog.com/doc/v8-stable/configuration/modules/imfile.html
I know you can open files from Symfony profiler or exception file links using this in project/app/config.yml :
framework:
ide: "phpstorm://open?file=%%f&line=%%l"
More info: http://developer.happyr.com/open-files-in-phpstorm-from-you-symfony-application
However as I'm using vagrant, the file path of the server doesn't match my host.
I have created a PHP web application server in PHPStorm with the propper path mappings, but still doesn't work.
Any ideas?
Thanks
When running your app in a container or in a virtual machine, you can tell Symfony to map files from the guest to the host by changing their prefix. This map should be specified at the end of the URL template, using & and > as guest-to-host separators:
// /path/to/guest/.../file will be opened
// as /path/to/host/.../file on the host
// as /path/to/host/.../file on the host
'phpstorm://%f:%l&/path/to/guest/>/path/to/host/&/foo/>/bar/&...'
Symfony FrameworkBundle Configuration - IDE
The answer given by Jeffry no longer works unfortunately :(. When In configure that with my paths the profiler throws:
ParameterNotFoundException
You have requested a non-existent parameter "f:".
I have configured the path according to this line in the SF docs: This map should be specified at the end of the URL template, which results in this:
phpstorm://open?url=file://%%f&line=%%l&/path/to/guest/>/path/to/host/
However, it does open PHPStorm, but phpstorm does not open the file, so i'm a bit stuck here now.
This solves the issue with the file not opening in PhpStorm from a Vagrant:
phpstorm://open?file=%%f&line=%%l&/path/to/guest/>/path/to/host/

has anyone tried to use a log4j.xml reference within a WinRun4j service configuration. here is a copy of my service.ini file. I have tried many configuration combinations. this is just my latest attempt
service.class=org.boris.winrun4j.MainService
service.id=SimpleBacnetIpDataTransfer
service.name=Simple Backnet IP DataTransfer Service
service.description=This is the service for the Simple Backnet IP DataTransfer.
service.startup=auto
classpath.1=C:\Inbox\DataTransferClient-1.0-SNAPSHOT-jar-with-dependencies.jar
classpath.2=WinRun4J.jar
classpath.3=C:\Inbox\log4j-1.2.16.jar
arg.1=C:\Inbox\DataTransferClient.xml
log=C:\WinRun4J-Service\SimpleBacnetIpDataTransfer\NBP-DT-service.log
log.overwrite=true
log.roll.size=10MB
[MainService]
class=com.shiftenergy.ws.App
vmarg.1=-Xdebug
vmarg.2=-Xnoagent
vmarg.3=-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n
vmarg.4=-Dlog4j.configuration=file:C:\Inbox\log4j.xml
within the log4j.xml file, there is reference to a log file for when the application runs. if I run the java -jar -Dlog4j.configuration=file:C:\Inbox\log4j.xml ...., the log file is created accordingly. if I register my service and start the service, the log file does not get created.
has anyone had success using the -D log4j configuration, using winrun4j?
thanks
I think that you provided the vmarg.4 parameter incorrectly. In your case it has to be like:
vmarg.4=-Dlog4j.configurationFile=[Path for log4j.xml]
I am also using the same and in my case, it is working perfectly fine. Please see below example:
vmarg.1=-Dlog4j.configurationFile=.\log4j2.xml
Have you tried setting the path in your code instead:
System.setProperty("log4j.configurationFile", "config/log4j.xml");
I'm using a relative path to a folder named config that contains log4j.xml. An absolute path is not recommended, but may work as well.
Just be sure to set this before making any calls to log4j, including any log4j config settings or static method calls!
System.setProperty("log4j.configurationFile", "config/log4j.xml");
final Logger log = Logger.getLogger(Main.class);
log.info("Starting up");
I didn't specify the log4j path in the ini file, only placed log4j.xml file at the same place the jar was placed.
Also without specify the
System.setProperty("log4j.configurationFile", "config/log4j.xml");
In the Java project it was stored in (src/main/resources) and will be included in the jar, but it will not be that one used if placed outside the jar.
I'm using Symfony 2 and have this row in my parameters.ini:
database_driver = pdo_pgsql
When I was creating database structure with Doctrine everything was good. But if I want to add some doctrine object to my darabase (insert row), I catch an exception:
What I have to do with this?
Are you sure you're using pdo_pgsql? Are you running on localhost? It might be very certain that you are using pdo_mysql driver instead.
However you have to check the following:
php.ini
extension=pdo.so
extension=pdo_mysql.so
or in your case
extension=pdo.so
extension=pdo_pgsql.so
You can check the phpinfo(); to find out the configured database driver.
In your symfony project you have to check the parameters.ini file in config folder. E.g.
[parameters]
database_driver="pdo_mysql"
database_host="localhost"
Besides try to avoid this error
'stty' is not recognized as an internal or external command,
operable program or batch file.
https://github.com/symfony/symfony/issues/4974
First of all, verify your php.ini file: the extensions php_pdo_pgsql and php_pdo must be enabled. Make sure you apply this changes on php.ini file that your symfony project is using, check this on localhost/path_to_your_project/web/config.php. You know if this extensions are enabled executing the function phpinfo().
This command is also helpfull: php -m. It lists on console all the php modules that are loaded.
Tip: check out you Apache error log, there could be something wrong with the load of your extensions. This file is located according to your server configuration.
