How to pass command line parameters to "vertx run"ContextI'm using continuous delivery and need to checkout a git branch then launch the verticle with a parameter.
For example:
I chekcout the "demo" git branchI deploy it to the target I remotely run the verticle with "vertx run 'demo'" (this actually doesn't work, but it illustrates my needs)The solution: use system environment variablesThe documentation https://vertx.io/docs/vertx-config/java/ is mentionning it, but it was not straight to me, so here is precisely how I did:
package org.rktmb.vertx // ... import io.vertx.config.ConfigStoreOptions; import io.vertx.config.ConfigRetriever; import io.vertx.config.ConfigRetrieverOptions; // ... public class MainVerticle extends SyncVerticle { @Override public void start(Future startFuture) throws Exception { // ... ConfigStoreOptions jsonEnvConfig = new ConfigStoreOptions().setType("env") .setConfig(new Js…

Using NPM to specify base-href
When building an Angular application, people usually use "ng" and pass arguments to that invocation.
Typically, when wanting to hard code "base-href" in "index.html", one will issue:

ng build --base-href='https://ngx.rktmb.org/foo'


I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin.
I got the habit to build the application with "npm run build" before deploying it.

But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter.

npm run build --base-href='https://ngx.rktmb.org/foo


did not set the base href in indext.html

After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says:
You need to use −− to pass arguments to npm scripts. This did the job!
The command to issue is then:

npm run build -- --base-href='https://ngx.rktmb.org/foo'

Where is the Database configuration file? I "often" have to change the database location from "localhost" to another one in the Atlassian products I use and I spend some amount of time figuring out where is the configuration stored.

Here I am.

Bamboo database configuration is in "bamboo-home/bamboo.cfg.xml"
Bitbucket database configuration is in "application-data/shared/bitbucket.properties"
Confluence database configuration is in "confluence/application-data/confluence.cfg.xml"
Jira database configuration is in "jira/application-data/dbconfig.xml"

How to move PostgreSQL datadirThe contextI run RHEL 7 and CentOS 7 .
The sysadmin team has setup a virtual machine for me and they put a big "/data" partition.
The default PostgreSQL installation usually use "/var/lib/pgsql" for PostgreSQL location.
I want to change it to "/data/pgsql"

How toStop PostgreSQL
systemctl stop postgresql
Move  "/var/lib/pgsql" and retain ownership & permissions
rsync -av /var/lib/pgsql /data/
Note: don't remove "/var/lib/pgsql" yet!

Configure "/data/pgsql/data/postgresql.conf" with the new location:
- #data_directory = 'ConfigDir'           + data_directory = '/data/pgsql/data'
Configure systemd service file "/usr/lib/systemd/system/postgresql.service"
- Environment=PGDATA=/var/lib/pgsql/data + Environment=PGDATA=/data/pgsql/data
Start PostgreSQLand check it all:
# systemctl start postgresql # systemctl status postgresql # ps aux | grep pgsql # su - postgres $ psql p…

How to make wget, curl and Maven download behind an NTLM Proxy
Working on CentOS, behind an NTLM proxy:
yum can deal without problem with a NTLM Proxywget, curl and Maven cannotThe solution is to use "cntlm".
"cntlm" is a NTLM client for proxies requiring NTLM authentication.

How it works
Install "cntlm"Configure "cntlm" by giving it your credentialsby giving it the NTLM Proxy Start "cntlm" deamon (it listens to "127.0.0.1:3128")Configure wget, curl and Maven to use "cntlm" instead of using directly the NTLM ProxyNote: You will have then a kind of 2 stages Proxy: cntlm + the NTLM proxy

Configure CNTLMAfter installing cntlm, the configuration file is in "cntlm.conf".

You must have your domain (in the Windows meaning), proxy login and  proxy password.
Mine are respectively: rktmb.org, mihamina, 1234abcd (yes, just for the example)

You must have you NTLM Proxy Hostnama or IP and port
Mine are respectively: prx.r…
