WARNING: no logs are available with the 'none' log driver - docker

I am following below url for logging driver
https://docs.docker.com/engine/admin/logging/overview/#configure-the-default-logging-driver
now, I want to remove this logging driver
I have remove file(daemon.json) from /etc/docker folder too.
But when I build container, system should always showing me warning
WARNING: no logs are available with the 'none' log driver
How can I get rid of this warning?

Finally solved.
1) Delete daemon.json file from /etc/docker folder.
2) Restart docker service.

My case.
In file docker-compose.yml it is very possible that you have:
logging:
driver: none
To get rid of the warning WARNING: no logs are available with the 'none' log driver you should comment or remove those 2 lines.

By default /etc/docker/daemon.json does not exist. The default driver is json-file. To verify current driver use
docker info | grep Logging
Logging Driver: fluentd
I use fluentd (td-agent) so my /etc/docker/daemon.json
{
"log-driver": "fluentd",
"log-opts": {
"fluentd-address": "127.0.0.1:24224"
}
}
For details about logging, divers see

Ansible connection to docker engine on osx apple Silicon

I'm trying to connect to my local docker engine running on OSX (m1 chip) in order to create a dynamic inventory.
I've created a host file with the following config
I made sure that docker_containers module is well installed.
plugin: community.docker.docker_containers
docker_host: "unix://Users/ME/.docker/run/docker-cli-api.sock"
Then I run ansible-inventory --graph -i ./hosts/hosts-docker-local.yaml.
But I'm getting the following error:
[WARNING]: * Failed to parse /Users/ME/Projects/ansible-test/hosts/hosts-docker-local.yaml with auto plugin: inventory source '/Users/ME/Projects/ansible-test/hosts/hosts-docker-local.yaml' could not be
verified by inventory plugin 'community.docker.docker_containers'
[WARNING]: * Failed to parse /Users/ME/Projects/ansible-test/hosts/hosts-docker-local.yaml with yaml plugin: Plugin configuration YAML file, not YAML inventory
[WARNING]: * Failed to parse /Users/ME/Projects/ansible-test/hosts/hosts-docker-local.yaml with ini plugin: Invalid host pattern 'plugin:' supplied, ending in ':' is not allowed, this character is reserved to

I tried
ansible-doc -t inventory -l | grep docker
community.docker.docker_containers Ansible dynamic inv...
community.docker.docker_machine Docker Machine inve...
community.docker.docker_swarm Ansible dynamic inv...
but somehow if I do this
ansible localhost -i ./hosts/hosts-docker-local.yaml -m community.docker.docker_containers
It complains
localhost | FAILED! => {
"msg": "The module community.docker.docker_containers was not found in configured module paths"
}
maybe something wrong with my module path, something wierd with OSX? (I installed Ansible with brew)
The inventory file must end in docker.yaml, as pointed out by #Zeitounator.
Uses a YAML configuration file that ends with docker.[yml|yaml].

Confluent Docker log4j logger level configurations

I am running locally Kafka using the confluentinc/cp-kafka Docker image and I am setting the following logging container environment variables:
KAFKA_LOG4J_ROOT_LOGLEVEL: ERROR
KAFKA_LOG4J_LOGGERS: >-
org.apache.zookeeper=ERROR,
org.apache.kafka=ERROR,
kafka=ERROR,
kafka.cluster=ERROR,
kafka.controller=ERROR,
kafka.coordinator=ERROR,
kafka.log=ERROR,
kafka.server=ERROR,
kafka.zookeeper=ERROR,
state.change.logger=ERROR
and I see in the Kafka logs that Kafka is starting with the following configuration:
===> ENV Variables ...
ALLOW_UNSIGNED=false
COMPONENT=kafka
CONFLUENT_DEB_VERSION=1
CONFLUENT_PLATFORM_LABEL=
CONFLUENT_VERSION=5.4.1
...
KAFKA_LOG4J_LOGGERS=org.apache.zookeeper=ERROR, org.apache.kafka=ERROR, kafka=ERROR, kafka.cluster=ERROR, kafka.controller=ERROR, kafka.coordinator=ERROR, kafka.log=ERROR, kafka.server=ERROR, kafka.zookeeper=ERROR, state.change.logger=ERROR
KAFKA_LOG4J_ROOT_LOGLEVEL=ERROR
...
Still I see further down in the logs the INFO and TRACE log levels. For example:
[2020-03-26 16:22:12,838] INFO [Controller id=1001] Ready to serve as the new controller with epoch 1 (kafka.controller.KafkaController)
[2020-03-26 16:22:12,848] INFO [Controller id=1001] Partitions undergoing preferred replica election: (kafka.controller.KafkaController)
[2020-03-26 16:22:12,849] INFO [Controller id=1001] Partitions that completed preferred replica election: (kafka.controller.KafkaController)
[2020-03-26 16:22:12,855] INFO [Controller id=1001] Skipping preferred replica election for partitions due to topic deletion: (kafka.controller.KafkaController)
How can I really deactivate the logs below a certain level? In the example above, I really want only ERROR logs.
The approach above is the way described in the Confluent documentation.
And the Apache Kafka source code lists all sorts of loggers that I could not influence using the KAFKA_LOG4J_LOGGERS Docker environment variable.
I went and troubleshot the Dockerfile's and inspected the Kafka container. The cause of this behaviour was the YAML multiline string folding.
Hence the provided environment variable (using a YAML multiline value) is at runtime:
KAFKA_LOG4J_LOGGERS=org.apache.zookeeper=ERROR, org.apache.kafka=ERROR, kafka=ERROR, kafka.cluster=ERROR, kafka.controller=ERROR, kafka.coordinator=ERROR, kafka.log=ERROR, kafka.server=ERROR, kafka.zookeeper=ERROR, state.change.logger=ERROR
instead of (no spaces in between):
KAFKA_LOG4J_LOGGERS=org.apache.zookeeper=ERROR,org.apache.kafka=ERROR, kafka=ERROR, kafka.cluster=ERROR,kafka.controller=ERROR, kafka.coordinator=ERROR,kafka.log=ERROR,kafka.server=ERROR,kafka.zookeeper=ERROR,state.change.logger=ERROR
And this was visible inside the container in the generated /etc/kafka/log4j.properties file:
log4j.rootLogger=ERROR, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %p %m (%c)%n
log4j.logger.kafka.authorizer.logger=WARN
log4j.logger.kafka.cluster=ERROR
log4j.logger.kafka.producer.async.DefaultEventHandler=DEBUG
log4j.logger.kafka.zookeeper=ERROR
log4j.logger.org.apache.kafka=ERROR
log4j.logger.kafka.coordinator=ERROR
log4j.logger.org.apache.zookeeper=ERROR
log4j.logger.kafka.log.LogCleaner=INFO
log4j.logger.kafka.controller=ERROR
log4j.logger.kafka=INFO
log4j.logger.kafka.log=ERROR
log4j.logger.state.change.logger=ERROR
log4j.logger.kafka=ERROR
log4j.logger.kafka.server=ERROR
log4j.logger.kafka.controller=TRACE
log4j.logger.kafka.network.RequestChannel$=WARN
log4j.logger.kafka.request.logger=WARN
log4j.logger.state.change.logger=TRACE
If you really need to split the long line in a YAML multiline value, you would have to use this YAML syntax.
More hints from the code:
here is where the log4j.properties file is generated when a confluent container is run.
these are the default log levels that Kafka will start with.
these should be all the loggers supported by Kafka

Starting Zabbix Server within docker replaces strings with nothing in config file →

→ or totally ignored strings like name of new DB for testing purposes.
Firstly tries to add something about ~250 to 250 already added hosts and Z-server shutted down. I've restarted it and inside docker logs I saw this:
6:20191014:091840.201 using configuration file: /etc/zabbix/zabbix_server.conf
6:20191014:091840.223 current database version (mandatory/optional): 04020000/04020001
6:20191014:091840.223 required mandatory version: 04020000
6:20191014:091840.484 __mem_malloc: skipped 7 asked 108424 skip_min 304 skip_max 12192
6:20191014:091840.484 [file:dbconfig.c,line:94] __zbx_mem_realloc(): out of memory (requested 108424 bytes)
6:20191014:091840.484 [file:dbconfig.c,line:94] __zbx_mem_realloc(): please increase CacheSize configuration parameter
6:20191014:091840.484 === memory statistics for configuration cache ===
Solution for those problem was to increase CacheSize in zabbix_server.conf . Okay, that's not a problem and after this Im push a new config to Z-server and restart it... → and z-server stops already after start and logs says the same problem. After reading config in container I saw what string what I corrected to matching my wishes are missing O_o. Strings are deleted.
My config:
LogType=console
DBHost=postgres-server
DBName=zabbix_pwd
DBSchema=public
DBUser=zabbix
DBPassword=zabbix
DBPort=5432
StartPollers=5
StartIPMIPollers=5
StartPollersUnreachable=5
SNMPTrapperFile=/var/lib/zabbix/snmptraps/snmptraps.log
StartSNMPTrapper=1
CacheSize=512M
HistoryCacheSize=512M
HistoryIndexCacheSize=512M
TrendCacheSize=512m
ValueCacheSize=256M
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
FpingLocation=/usr/sbin/fping
Fping6Location=/usr/sbin/fping6

SSLKeyLocation=/var/lib/zabbix/ssl/keys/
SSLCALocation=/var/lib/zabbix/ssl/ssl_ca/
LoadModulePath=/var/lib/zabbix/modules/
And what I've getting after starting z-server:
LogType=console
DBHost=postgres-server
DBName=zabbix_pwd
DBSchema=public
DBUser=zabbix
DBPassword=zabbix
DBPort=5432
SNMPTrapperFile=/var/lib/zabbix/snmptraps/snmptraps.log
StartSNMPTrapper=1
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
FpingLocation=/usr/sbin/fping
Fping6Location=/usr/sbin/fping6
SSHKeyLocation=/var/lib/zabbix/ssh_keys
SSLCertLocation=/var/lib/zabbix/ssl/certs/
SSLKeyLocation=/var/lib/zabbix/ssl/keys/
SSLCALocation=/var/lib/zabbix/ssl/ssl_ca/
LoadModulePath=/var/lib/zabbix/modules/
Any suggestions to how-to rule the world and don't be captured by doctors ?
With docker you need to send conf parameters in the docker-compose.yml file, or in your docker run command using the -e :
For example from my docker yml file:
zabbix-server:
image: zabbix/zabbix-server-pgsql:ubuntu-4.2.6
environment:
ZBX_MAXHOUSEKEEPERDELETE: 5000
ZBX_STARTPOLLERS: 15
ZBX_CACHESIZE: 8M
ZBX_STARTDBSYNCERS: 4
ZBX_HISTORYCACHESIZE: 16M
ZBX_TRENDCACHESIZE: 4M
ZBX_VALUECACHESIZE: 8M
ZBX_LOGSLOWQUERIES: 3000

Daphne not logging errors

I have the following systemd config
[Service]
WorkingDirectory=/srv/www/project_a/project_a/
Environment=JSON_SETTINGS=/srv/www/project_a/project_a.json
ExecStart=/srv/www/project_a/bin/daphne -b 0.0.0.0 -p 8000 project_a.asgi:channel_layer
Restart=always
KillSignal=SIGTERM
NotifyAccess=all
StandardOut=file:/tmp/daphne-access.log
StandardError=file:/tmp/daphne-error.log
But the daphne-access.log and daphone-error.log files are both empty, I thought daphne's default logging out be outputting to stdout?
Tried: --access-log=/tmp/daphne-access.log which worked for access logs, but don't know where to get django errors when they happen.
Just add the following to your LOGGING['loggers'] settings:
'daphne': {
'handlers': [
'console',
],
'level': 'DEBUG'
},
For django errors you need to define django logs. please refer the documentation for more information.

Homebrew: Can't start elastic search

I'm in a big trouble, I can't start Elasticsearch and I need it for run my rails locally, please tell me what's going on. I installed Elasticsearch in the normal fashion then I did the following:
elasticsearch --config=/usr/local/opt/elasticsearch/config/elasticsearch.yml
But it shows the following error: [2015-11-01 20:36:50,574][INFO ][bootstrap] es.config is no longer supported. elasticsearch.yml must be placed in the config directory and cannot be renamed.
I tried several alternative ways of run it, like:
elasticsearch -f -D
But then I get the following error, and I can't find any useful for solve it, it seems to be related with file perms but not sure:

Thanks for your help.
There are some changes with libexec with Elasticsearch/homebrew installation and that is why it is failing to start. There is a PR #45644 currently being worked on. Till the PR gets accepted, you can use the same formula to fix the installation of Elasticsearch.
First uninstall the earlier/older version. Then edit the formula of Elasticsearch:
$ brew edit elasticsearch
And use the formula from the PR.
Then do brew install elasticsearch, it should work fine.
To start Elasticsearch, just do:
$ elasticsearch
config option is no longer valid. For custom config, use path.config:
$ elasticsearch --path.conf=/usr/local/opt/elasticsearch/config
