Convert Command-Line Options to YAML
Starting in MongoDB 4.2, mongod
and mongos
accept --outputConfig
command-line option to output the configuration used by the mongod
/mongos
instance.
You can use this option to convert command-line options to YAML configuration.
Examples
Convert mongod
Command-Line Options to YAML
Consider the following mongod
invocation that uses the command-line options:
mongod --shardsvr --replSet myShard --dbpath /var/lib/mongodb --bind_ip localhost,My-Example-Hostname --fork --logpath /var/log/mongodb/mongod.log --clusterAuthMode x509 --tlsMode requireTLS --tlsCAFile /path/to/my/CA/file --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file
Include the --outputConfig
command-line option to generate the corresponding YAML file.
copycopied
mongod --shardsvr --replSet myShard --dbpath /var/lib/mongodb --bind_ip localhost,My-Example-Hostname --fork --logpath /var/log/mongodb/mongod.log --clusterAuthMode x509 --tlsMode requireTLS --tlsCAFile /path/to/my/CA/file --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file --outputConfig
The mongod
outputs the following YAML to stdout
and exits:
copycopied
net:
bindIp: localhost,My-Example-Hostname
tls:
CAFile: /path/to/my/CA/file
certificateKeyFile: /path/to/my/certificate/file
clusterFile: /path/to/my/cluster/membership/file
mode: requireTLS
outputConfig: true
processManagement:
fork: true
replication:
replSet: myShard
security:
clusterAuthMode: x509
sharding:
clusterRole: shardsvr
storage:
dbPath: /var/lib/mongodb
systemLog:
destination: file
path: /var/log/mongodb/mongod.log
To create a configuration file, copy the generated content into a file and delete the outputConfig
setting from the YAML.
Convert mongos
Command-Line Options to YAML
Consider the following mongos
invocation that uses the command-line options:
mongos --configdb myCSRS/cfg1.example.net:27019,cfg2.example.net:27019 --bind_ip localhost,My-Example-MONGOS-Hostname --fork --logpath /var/log/mongodb/mongos.log --clusterAuthMode x509 --tlsMode requireTLS --tlsCAFile /path/to/my/CA/file --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file
Include the --outputConfig
command-line option to generate the corresponding YAML for the mongos
instance:
copycopied
mongos --configdb myCSRS/cfg1.example.net:27019,cfg2.example.net:27019 --bind_ip localhost,My-Example-MONGOS-Hostname --fork --logpath /var/log/mongodb/mongos.log --clusterAuthMode x509 --tlsMode requireTLS --tlsCAFile /path/to/my/CA/file --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file --outputConfig
The mongos
outputs the following YAML to stdout
and exits:
copycopied
net:
bindIp: localhost,My-Example-MONGOS-Hostname
tls:
CAFile: /path/to/my/CA/file
certificateKeyFile: /path/to/my/certificate/file
clusterFile: /path/to/my/cluster/membership/file
mode: requireTLS
outputConfig: true
processManagement:
fork: true
security:
clusterAuthMode: x509
sharding:
configDB: myCSRS/cfg1.example.net:27019,cfg2.example.net:27019
systemLog:
destination: file
path: /var/log/mongodb/mongos.log
To create a configuration file, copy the generated content into a file and delete the outputConfig
setting from the YAML.
