Nomad execution environment missing PORT/IP variables from other tasks

[robothor]

Nomad version

Nomad v0.5.5

Operating system and Environment details

Ubuntu 14.04.4 LTS

Issue

Not all task ports are exposed to all tasks. I have three tasks in this example. Two tasks expose multiple ports (port "yours" {} and port "mine" {} from one and ports "one", "two", "three" from another) .

However, when from the environment of the third task, only the last port/ip is visible:

(from /usr/bin/env)

NOMAD_ADDR_mtl_example_three=10.45.10.151:59824
NOMAD_ADDR_mtl_sleep_mine=10.45.10.151:41048
NOMAD_ALLOC_DIR=/alloc
NOMAD_ALLOC_ID=10b3fbdb-44a4-fa00-468b-cf37dc715a42
NOMAD_ALLOC_INDEX=0
NOMAD_ALLOC_NAME=mtl-example.mtl-test[0]
NOMAD_CPU_LIMIT=100
NOMAD_IP_mtl_example_three=10.45.10.151
NOMAD_IP_mtl_sleep_mine=10.45.10.151
NOMAD_JOB_NAME=mtl-example
NOMAD_MEMORY_LIMIT=100
NOMAD_PORT_mtl_example_three=59824
NOMAD_PORT_mtl_sleep_mine=41048
NOMAD_SECRETS_DIR=/secrets
NOMAD_TASK_DIR=/local
NOMAD_TASK_NAME=mtl-env

Reproduction steps

If I run the attached job, all three tasks start. (https://gist.github.com/robothor/611a2b54d9a5a5294b215f39a44671e4)

Running nomad logs 10b3fbdb mtl-env | grep NOMAD | sort -u

produces the above output showing the environment in the third task.

I expect to see

NOMAD_PORT_mtl_example_one=XXXXX
NOMAD_PORT_mtl_example_two=YYYYY
NOMAD_PORT_mtl_example_three=59824
NOMAD_PORT_mtl_sleep_yours=ZZZZZ
NOMAD_PORT_mtl_sleep_mine=41048

I also expect to see the corresponding NOMAD_ADDR and NOMAD_IP variables.
