fluentbit-replica

fluentbit changes for replicaset

Update the td-agent-bit.conf

Update container.conf file in this path: /etc/opt/microsoft/omsagent//conf/omsagent.d restart omsagent: /opt/microsoft/omsagent/bin/service_control restart

Start fluent-bit with this conf file: /opt/td-agent-bit/bin/td-agent-bit -c /etc/td-agent-bit/td-agent-bit.conf

To build an output plugin: You will need an so file generated. Install and configure go using this link: https://www.linode.com/docs/development/go/install-go-on-ubuntu/ ( make sure to install version 1.10 and above or it will fail with string errors) (or https://medium.com/@patdhlk/how-to-install-go-1-9-1-on-ubuntu-16-04-ee64c073cd79) follow the first link to configure paths properly. Create folder in $HOME/go/src/KPI Create a file out_kubepodinventory.go Try go build. If it fails with package not found errors: go get "pkg-name from errors" go build -buildmode=c-shared -o out_kubepodinventory.so . Try ldd out_kubepodinventory.so Output should look like this: rashmi@rashmi-linux-go:~/go/src/KPI$ ldd out_kubepodinventory.so linux-vdso.so.1 => (0x00007fff527a3000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9992e99000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9992acf000) /lib64/ld-linux-x86-64.so.2 (0x00007f9994ff3000)

#install fluentbit on omsagent's pod

wget -qO - https://packages.fluentbit.io/fluentbit.key | sudo apt-key add -

sudo echo "deb https://packages.fluentbit.io/ubuntu/xenial xenial main" >> /etc/apt/sources.list

sudo apt-get update

sudo apt-get install td-agent-bit sqlite3 libsqlite3-dev

#start fluent-bit

/opt/td-agent-bit/bin/td-agent-bit -c /etc/td-agent-bit/td-agent-bit.conf -e

#To run multiple plugins, /opt/td-agent-bit/bin/td-agent-bit -c /etc/td-agent-bit/td-agent-bit.conf -e -e <path to another .so file>

#To forward to a port and get the output from the input plugin, make the changes in the conf file - td-agent-bit.conf and container.conf Make sure to run the fluentbit before restarting the omsagent. If the fluentbit is not running when the omsagent is restarted things dont work as expected.
