In honor of Docker’s fourth birthday, we will be writing a series of articles describing how to get started with logging a Dockerized environment with ELK. While it is not always easy and straightforward to set up an ELK pipeline (the difficulty is determined by your environment specifications), the end result can look like this Kibana monitoring dashboard for Docker logs: The ELK Stack (Elasticsearch, Logstash and Kibana) is one way to overcome some, if not all, of these hurdles. Transiency, distribution, isolation - all of the prime reasons that we opt to use containers for running our applications are also the causes of huge headaches when attempting to build an effective centralized logging solution. Used for advanced log tag options.The irony one faces when trying to log Docker containers is that the very same reason we chose to use them in our architecture in the first place is also the biggest challenge. A regular expression to match logging-related environment variables. Used for advanced log tag options.Īpplies when starting the Docker daemon. A comma-separated list of logging-related environment variables this daemon accepts. log-opt labels-regex=^(production_status\|geo)Īpplies when starting the Docker daemon. A regular expression to match logging-related labels. A comma-separated list of logging-related labels this daemon accepts. Specify rfc3164 for the RFC-3164 compatible format, rfc5424 for RFC-5424 compatible format, or rfc5424micro for RFC-5424 compatible format with microsecond timestamp resolution.Īpplies when starting the Docker daemon. If not specified the local UNIX syslog format is used, without a specified hostname. Refer to the log tag option documentation for customizing the log tag format. By default, Docker uses the first 12 characters of the container ID to tag log messages. Ignored if the address protocol is not tcp+tls.Ī string that is appended to the APP-NAME in the syslog message.

If set to true, TLS verification is skipped when connecting to the syslog daemon. log-opt syslog-tls-key=/etc/ca-certificates/custom/key.pem Ignored if the address protocol is not tcp+tls. log-opt syslog-tls-cert=/etc/ca-certificates/custom/cert.pem The absolute path to the TLS certificate file. log-opt syslog-tls-ca-cert=/etc/ca-certificates/custom/ca.pem The absolute path to the trust certificates signed by the CA.

Can be the number or name for any valid syslog facility. If the transport is tcp, udp, or tcp+tls, the default port is 514. The URI specifier may be ://host:port, unix://path, or unixgram://path. The address of an external syslog server. They can also be set on a givenĬontainer by adding a -log-opt = flag for each option when Key-value pairs to the log-opts JSON array. They can be set as defaults in the daemon.json, by adding them as The following logging options are supported as options for the syslog loggingĭriver. $ docker run \ -log-driver syslog -log-opt syslog-address =udp://1.2.3.4:1111 \ The syslog-address options supports both UDP and TCP

The following example sets the log driver to syslog and sets the For more aboutĬonfiguring Docker using daemon.json, see

Located in /etc/docker/ on Linux hosts orĬ:\ProgramData\docker\config\daemon.json on Windows Server. To use the syslog driver as the default logging driver, set the log-driverĪnd log-opt keys to appropriate values in the daemon.json file, which is The format is defined in RFC 5424 and Docker’s syslog driver implements theĪBNF reference in the following way: TIMESTAMP SP HOSTNAME SP APP-NAME SP PROCID SP MSGID

Receiver can extract the following information: Message must be formatted in a specific way to be valid. The syslog protocol usesĪ raw string as the log message and supports a limited set of metadata. The syslog logging driver routes logs to a syslog server.
