Hi All,
In my environment running mesos-slave, mesos-master marathon and mesos-dns
in standalone mode.
I deployed mysql app to marathon to run as docker container.
MySql app configurations as follows.
{
"id": "mysql",
"cpus": 0.5,
"mem": 512,
"instances": 1,
"container": {
"type": "DOCKER",
"docker": {
"image": "mysql:5.6.27",
"network": "BRIDGE",
"portMappings": [
{
"containerPort": 3306,
"hostPort": 32000,
"protocol": "tcp"
}
]
}
},
"constraints": [
[
"hostname",
"UNIQUE"
]],
"env": {
"MYSQL_ROOT_PASSWORD": "password"
},
"minimumHealthCapacity" :0,
"maximumOverCapacity" : 0.0
}
Then I deploy app called mysql client. Mysql client app needs to connect to
mysql app.
mysql app config as follows.
{
"id": "mysqlclient",
"cpus": 0.3,
"mem": 512.0,
"cmd": "/scripts/create_mysql_dbs.sh",
"instances": 1,
"container": {
"type": "DOCKER",
"docker": {
"image": "mysqlclient:latest",
"network": "BRIDGE",
"portMappings": [{
"containerPort": 3306,
"hostPort": 0,
"protocol": "tcp"
}]
}
},
"env": {
"MYSQL_ENV_MYSQL_ROOT_PASSWORD": "password",
"MYSQL_PORT_3306_TCP_ADDR": "mysql.marathon.slave.mesos.",
"MYSQL_PORT_3306_TCP_PORT": "32000"
},
"minimumHealthCapacity" :0,
"maximumOverCapacity" : 0.0
}
>From the host machines I can ping to mysql.marathon.slave.mesos. But from
the mysql client docker conatiner I couldnt reach host
"mysql.marathon.slave.mesos."
My mess-dns configurations as follows.
{
"zk": "zk://127.0.0.1:2181/mesos",
"masters": ["127.0.0.1:5050"],
"refreshSeconds": 60,
"ttl": 60,
"domain": "mesos",
"port": 53,
"resolvers": ["127.0.0.1"],
"timeout": 5,
"httpon": true,
"dnson": true,
"httpport": 8123,
"externalon": true,
"listener": "127.0.0.1",
"SOAMname": "ns1.mesos",
"SOARname": "root.ns1.mesos",
"SOARefresh": 60,
"SOARetry": 600,
"SOAExpire": 86400,
"SOAMinttl": 60,
"IPSources": ["mesos", "host"]
}
*I tried with giving dns as parameter to mysql client app. But that also
not work. What is the reason for this?*
Thanks
