Highlight outputs in karaf gogo shell

The command shell:highlight in mhus-osgi-tools 1.3.5 will provide a command to search and highlight text via pipe:

The basic usage are:

service:list | highlight bundle

The command accept regex expressions and by default the regex is case insensitive, the result is:

[org.osgi.service.url.URLStreamHandlerService]
----------------------------------------------
 service.bundleid = 51
 service.id = 31
 service.scope = singleton
 url.handler.protocol = [wrap]
Provided by : 
 OPS4J Pax Url - wrap: (51)
Used by: 
 Apache Karaf :: Deployer :: Wrap Non OSGi Jar (28)
 System Bundle (0)

More complex is the the option to search multiple words and change the color for each finding:

service:list | highlight \#blue bundle \#green service

The result:

[org.osgi.service.url.URLStreamHandlerService]
----------------------------------------------
 service.bundleid = 51
 service.id = 31
 service.scope = singleton
 url.handler.protocol = [wrap]
Provided by : 
 OPS4J Pax Url - wrap: (51)
Used by: 
 Apache Karaf :: Deployer :: Wrap Non OSGi Jar (28)
 System Bundle (0)

A nice feature to manipulate text output is the option to set a start and stop marker for findings. This is useful for a non color terminal:

service:list | highlight \#a[ \#o] service

The result:

[org.osgi.[service].url.URLStreamHandler[Service]]
----------------------------------------------
 [service].bundleid = 51
 [service].id = 31
 [service].scope = singleton
 url.handler.protocol = [wrap]
Provided by : 
 OPS4J Pax Url - wrap: (51)
Used by: 
 Apache Karaf :: Deployer :: Wrap Non OSGi Jar (28)
 System Bundle (0)

With more options it’s possible to switch on case sensitive '#Ion' or set background color '#Bblue'.

Sonatype Nexus fails with random "peer not authenticated" errors behind ingress

 After installing nexus3 server in a kubernetes environment in the first view everything looks good. Server is running an accessible from the world. Users and roles are defined and working. But already in the first hours of working with the repository there are problems. The trick was retry the failed activity and everything went ok. It turned out that heavy activities failed a lot of times and a lot of retries have to be done to finish the tasks. Annoying if a release deploy failed. You need to increase the version number every time. There were a few support in the internet for the problems most of the time handling SSL problems between maven and nexus. But it did not fix the problem. It looks like maven and the used http library wagon have got problems with pooled connections if using ingress (a test with a standalone installation did not show the problem)  - The 'deep' reason is not really clear for me, need to invest more time for it. The solution is to deny wagon to use po

Creating a flux sync configuration referring a config map for substitution

 If you configure your k8s cluster with terraform one of the final steps is to install a fluxcd operator. The operator are responsible to manage the resources inside of the cluster. In this way a fully automatic creation process is possible. To install flux a terraform provider is available preparing a install and sync configuration which can be installed in k8s using the kubernetes/kubectl providers. In fluxcd itself it is possible to use substitution . This means you can use variables to prepare the k8s yaml files. This is useful for variable content like different cluster names and domain names for all stages. Or more specialised arn ids of created resources while creating the cluster in aws. To use substitution fluxcd offers to link the configuration to a config map. In the map a set of key values can be defined to replace variable values. The map can also be created with terraform and the kubectl provider. Do not store secrets in the config map. Try to use secrets instead. Applyi
