skywalking oap server docker image problem

[hieu276]

OAP image: apache/skywalking-oap-server:9.2.0
UI image: apache/skywalking-ui:9.2.0
I tried running skywalking on docker by using skywalking images version 9 and faced problem when loading ui (in following image) . I have the same problem when running skywalking distribution in ubuntu 22.04. If i run oap-server in my local host, it work perfectly with ui container.

This is my docker-compose.yml

version: '3'
services:
  oap:
    image: apache/skywalking-oap-server:9.2.0
    container_name: oap
    restart: always
    ports:
      - 11800:11800 
      - 12800:12800 
    environment:
      - SW_STORAGE=elasticsearch
      - SW_STORAGE_ES_CLUSTER_NODES=elasticsearch:9200
      - TZ=Asia/Ho_Chi_Minh
  skywaling-ui:
    image: apache/skywalking-ui:9.2.0
    container_name: ui
    depends_on:
      - oap
    links:
      - oap
    ports:
      - 8009:8080
    environment:
      - SW_OAP_ADDRESS=oap:12800

My problem:

[hieu276]

i built some oap images on other base: centos, ubuntu, red hat but nothing works

Where is the elasticsearch container? What is the status of the OAP/UI containers? How did you run locally successfully?

Asking this kind of questions is a waste of time, you basically gave nothing useful

@kezhenxu94 Thank you a lot. i should learn more about making a question. Should i provide more useful information here or delete and recreate new post.

Just supplement information here

adding elasticsearch doesn't work, i got the same error.
my docker-compose

services:
  elasticsearch:
    image: elasticsearch:7.17.6
    container_name: elasticsearch
    ports:
      - 9200:9200
    environment:
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
  oap:
    image: apache/skywalking-oap-server:9.2.0
    container_name: oap
    restart: always
    ports:
      - 11800:11800 
      - 12800:12800 
    environment:
      - SW_STORAGE=elasticsearch
      - SW_STORAGE_ES_CLUSTER_NODES=elasticsearch:9200
      - TZ=Asia/Ho_Chi_Minh
  skywaling-ui:
    image: apache/skywalking-ui:9.2.0
    container_name: ui
    depends_on:
      - oap
    links:
      - oap
    ports:
      - 8020:8080
    environment:
      - SW_OAP_ADDRESS=oap:12800

container status

For the third question, i lunch script oapService.sh in /bin folder and start ui container: docker run --name ui --restart always -d -e SW_OAP_ADDRESS=http://192.168.29.128:12800 apache/skywalking-ui:9.2.0

Your docker-compose.yaml is rather wrong. There is a docker-compose.yaml in skywalking codebase, if you choose to write your own, debug by yourself.

I used docker-compose.yml in skywalking code base.

ES_VERSION = 7.10.2-amd64
OAP_IMAGE = apache/skywalking-oap-server:9.2.0
UI_IMAGE = apache/skywalking-ui:9.2.0
https://github.com/apache/skywalking/blob/master/docker/docker-compose.yml

i got error "for ui Container "fdb4c1fb583d" is unhealthy". fdb4c1fb583d is my oap container.
i inspected log in oap container.

"Log": [

                    },
                    {
                        "Start": "2022-10-13T08:59:02.959903164+07:00",
                        "End": "2022-10-13T08:59:03.159732708+07:00",

                        "Output": "/bin/sh: 1: /skywalking/bin/swctl: not found\n"
                    },
                    {
                        "Start": "2022-10-13T08:59:33.1670865+07:00",
                        "End": "2022-10-13T08:59:33.375371236+07:00",
                        "ExitCode": 127,
                        "Output": "/bin/sh: 1: /skywalking/bin/swctl: not found\n"
                    }
                ]

How do i install swctl in container? Or do i must build a new oap image that install swctl?

[kezhenxu94]

I believe swctl is already bundled in official OAP images. Not sure what you did to those images.

$ docker run -it --rm --entrypoint bash apache/skywalking-oap-server:9.2.0 -c "ls -alh /skywalking/bin"
