Este é meu Dockerfile

FROM ubuntu:22.04

RUN apt update
RUN apt upgrade -y
RUN apt install -y curl git jq libicu70

# Also can be "linux-arm", "linux-arm64".
ENV TARGETARCH="linux-x64"

WORKDIR /azp/

COPY ./azsh-linux-agent/start.sh ./
RUN chmod +x ./start.sh

RUN useradd agent
RUN chown agent ./
USER agent
ENTRYPOINT ./start.sh

Eu tento construir uma imagem, a partir de pwd

/home/jh/azsh-linux-agent

Recebi um erro quando tentei construir

docker build --tag "azsh-linux-agent:1.0" --file "./azsh-linux-agent.dockerfile" .

assim

--------------------

  13 |     RUN chmod +x ./start.sh

por que o script não é detectado?

Package libnetfilter_queue was not found in the pkg-config search path.
Perhaps you should add the directory containing `libnetfilter_queue.pc'
to the PKG_CONFIG_PATH environment variable

Estou no Ubuntu 22.04.

Estou tendo problemas com o código legado da empresa. Dockerfile

FROM mycomp/tech:2.13

RUN rm -Rf /opt/app/src/api

COPY src/ /opt/app/src/
COPY config.json /opt/app/config.json

serve para que RUN rm -Rf? Por que o cara que escreveu o Dockerfile o adicionou? Como ele será mapeado no contêiner?

Isso deveria ser trivial, mas parece que não é. Formatei meu comp e instalei o conda (estou acostumado com esta ferramenta de pacote)

pip install awscli --upgrade --user
Requirement already up-to-date: awscli in ./.local/lib/python3.7/site-packages (1.16.313)

Mas agora estou com problema

aws --version

Command 'aws' not found, but can be installed with:

sudo snap install aws-cli  # version 1.16.266, or
sudo apt  install awscli

eu tentei

sudo apt  install awscli
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package awscli is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'awscli' has no installation candidate

Atualizei e atualizei minha distro para não ver nenhum problema desse lado. Como consertar isto?

instalação instantânea

error: This revision of snap "aws-cli" was published using classic confinement
       and thus may perform arbitrary system changes outside of the security
       sandbox that snaps are usually confined to, which may put your system at
       risk.

       If you understand and want to proceed repeat the command including
       --classic.

Agora eu quero mudar as permissões

/opt/hadoop-3.2.0$ whoami
miki

Meu objetivo é que miki seja o dono de todos os arquivos do hadoop-3.2.0. Acho que devo usar chmod? Como deve ser o comando?

Eu estava instalando o Hadoop no meu Ubuntu.

Este é o meu CAMINHO agora

echo $PATH
/usr/lib/jvm/java-1.11.0-openjdk-amd64/bin:/home/miki/.local/bin:/opt/hadoop-3.2.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

Se eu tentarll

miki@miki:~$ ll
ll: command not found

Minha linha de edição bashrc

echo 'export HADOOP_HOME=/opt/hadoop-3.2.0;export PATH=$HADOOP_HOME/bin:$PATH' > ~/.bashrc

o arquivo ~/.bashrc tem apenas uma linha

export HADOOP_HOME=/opt/hadoop-3.2.0

Todos os scripts anteriores foram excluídos.

Também é estranho que as letras tenham mudado de cor. Por quê?

Tentei novamente abrir 22

sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT

mas ainda não vejo 22 com netstat

netstat -tpln | grep 22

Como resolver este problema?

RESOLVIDO Era um problema de sshd. Limpei e instalei o servidor OpenSSH.

Eu queria verificar o tamanho do backup do meu sistema de arquivos

ls -lia backup.tgz 
17 -rw-r--r-- 1 root root 84972633333 мај 28 10:05 backup.tgz

Com tamanho de bloco M

 ls -l --block-size=M backup.tgz 
-rw-r--r-- 1 root root 81037M мај 28 10:05 backup.tgz

Finalmente com tamanho de bloco G

ls -l --block-size=G backup.tgz 
-rw-r--r-- 1 root root 80G мај 28 10:05 backup.tgz

Alguém poderia explicar uma diferença tão grande?

Meu código

docker-machine create --driver virtualbox dev

Então

eval "$(docker-machine env dev)"

Meu objetivo era verificar com echo

echo $dev

O próximo passo é atualizar

Err:22 https://packagecloud.io/AtomEditor/atom/ubuntu bionic Release    
  404  Not Found [IP: 54.241.144.200 443]

Experimentei as sugestões do Rui

root@miki:/etc/apt/sources.list.d# mv AtomEditor_atom.list deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main

Isto mostra

mv: target 'main' is not a directory

Como resolver este erro?

RESOLVIDO Primeiro apagou o arquivo, depois

sudo sh -c 'echo "deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main" > /etc/apt/sources.list.d/atom.list'
