Docker add Portmapping in existing Container

 Just got this from:

https://stackoverflow.com/questions/19335444/how-do-i-assign-a-port-mapping-to-an-existing-docker-container

or:

https://mybrainimage.wordpress.com/2017/02/05/docker-change-port-mapping-for-an-existing-container/

If you run docker run <NAME> it will spawn a new image, which most likely isn't what you want.

If you want to change a current image do the following:

docker ps -a

Take the id of your target container and go to:

cd /var/lib/docker/containers/<conainerID><and then some:)>

Stop the container:

docker stop <NAME>

Change the files

vi config.v2.json

"Config": {
    ....
    "ExposedPorts": {
        "80/tcp": {},
        "8888/tcp": {}
    },
    ....
},
"NetworkSettings": {
....
"Ports": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],

And change file

vi hostconfig.json

"PortBindings": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],
     "8888/tcp": [
         {
             "HostIp": "",
             "HostPort": "8888"
         } 
     ]
 }

Restart your docker and it should work.

influx Install and backup/move

 Influx install:

Influx Backup:

Also ich mache mein Backup von der normalen Linux Kommandozeile aus und nicht unter der Influxdb-Konsole...

Das schaut dann so aus bei meiner Datenbank die iobroker heißt:

Vorher muss aber die Influxdb.config bearbeitet werden...:

Hatte mich damals hiernach gerichtet und entsprechend meinen Anforderungen umgesetzt...:

https://solaranzeige.de/phpBB3/viewtopic.php?t=310

Einen Restore hatte ich auch schon gemacht - ging problemlos.

https://solaranzeige.de/phpBB3/viewtopic.php?t=310

Recently I got an error on influxdb. The log file was not clearly stating an error. But Health target was not reached. Starting the service stated to read the error log, journalctl -xe .

Finally I saw the config pattern:

LimitNOFILE=65536 which basically could limit the number of files the service oder user??? can occupy.

After commenting with # . The service starts succesfully.

This is not due to the case having more than 65k open, but perhaps in contradiction to system limits .

This solved my issues on ubuntu but not on my original raspbian.

ESP2866-01 Wiring

 Some ESP8266-01 Boards need the Ping CH_PD pulled, high, otherwise it is in rest mode.

Pulled high means putting a 10kOhm resistor between CH_PD and VCC.
