Here is a working wordpress/mysql set that goes through consul connect and works with -dev-connect.
job "wordpress" {
datacenters = ["fin1"]
group "database" {
network {
mode = "bridge"
}
service {
name = "database"
port = 3306
tags = ["production", "mariadb"]
connect {
sidecar_service {}
}
}
task "database" {
driver = "docker"
config {
image = "mariadb"
}
env {
MYSQL_RANDOM_ROOT_PASSWORD = "yes"
MYSQL_INITDB_SKIP_TZINFO = "yes"
MYSQL_DATABASE = "exampledb"
MYSQL_USER = "exampleuser"
MYSQL_PASSWORD = "examplepass"
}
resources {
cpu = 100
memory = 128
}
}
}
group "server" {
network {
mode = "bridge"
port "http" {
static = 8080
to = 80
}
}
service {
name = "wordpress"
port = "8080"
tags = ["production", "wordpress"]
connect {
sidecar_service {
proxy {
upstreams {
destination_name = "database"
local_bind_port = 3306
}
}
}
}
}
task "server" {
driver = "docker"
config {
image = "wordpress"
}
env {
WORDPRESS_DB_HOST = "${NOMAD_UPSTREAM_ADDR_database}"
WORDPRESS_DB_USER = "exampleuser"
WORDPRESS_DB_PASSWORD = "examplepass"
WORDPRESS_DB_NAME = "exampledb"
}
resources {
cpu = 100
memory = 64
}
}
}
}
Now, another one that does not work:
job "wordpress" {
datacenters = ["fin1"]
group "database" {
network {
mode = "bridge"
port "db" {
to = 3306
}
}
service {
name = "database"
port = "db"
tags = ["production", "mariadb"]
connect {
sidecar_service {}
}
}
task "database" {
driver = "docker"
config {
image = "mariadb"
}
env {
MYSQL_RANDOM_ROOT_PASSWORD = "yes"
MYSQL_INITDB_SKIP_TZINFO = "yes"
MYSQL_DATABASE = "exampledb"
MYSQL_USER = "exampleuser"
MYSQL_PASSWORD = "examplepass"
}
resources {
cpu = 100
memory = 128
}
}
}
group "server" {
network {
mode = "bridge"
port "http" {
static = 8080
to = 80
}
}
service {
name = "wordpress"
port = "8080"
tags = ["production", "wordpress"]
connect {
sidecar_service {
proxy {
upstreams {
destination_name = "database"
local_bind_port = 3306
}
}
}
}
}
task "server" {
driver = "docker"
config {
image = "wordpress"
}
env {
WORDPRESS_DB_HOST = "${NOMAD_UPSTREAM_ADDR_database}"
WORDPRESS_DB_USER = "exampleuser"
WORDPRESS_DB_PASSWORD = "examplepass"
WORDPRESS_DB_NAME = "exampledb"
}
resources {
cpu = 100
memory = 64
}
}
}
}
For sake of readability, the only change affects the database. In particular, the non working example uses:
network {
mode = "bridge"
port "db" {
to = 3306
}
}
service {
name = "database"
port = "db"
tags = ["production", "mariadb"]
connect {
sidecar_service {}
}
}
while the working one has:
network {
mode = "bridge"
}
service {
name = "database"
port = 3306
tags = ["production", "mariadb"]
connect {
sidecar_service {}
}
}
Why is this?
