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:
https://www.verdrahtet.info/2020/02/14/installation-von-influxdb-grafana-inkl-verbindung-zu-iobroker/
Influx Backup:
https://forum.iobroker.net/post/429747
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...:

Einen Restore hatte ich auch schon gemacht - ging problemlos.

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.
